kn-abstract=Enhancing antioxidant function is a key strategy for preventing and treating oxidative stress-related diseases. Radon inhalation and thermal treatment (TT) increase the levels of antioxidant enzymes, such as superoxide dismutase (SOD). The positive effects of this combination on pain-related diseases have been reported; however, few studies have elucidated the underlying mechanisms. In this study, we examined the enhancement of antioxidant function in various organs of mice subjected to combined TT and radon inhalation. The mice were placed in an incubator once daily for 40 min at 38.5 ± 0.5°C and treated for 1, 3 and 7 days. The mice then inhaled radon at a concentration of 2000 Bq/m3 for 24 h. The characteristic changes in antioxidant function following combined TT and radon inhalation could be categorized into four groups: (i) increased antioxidant function in the brain and colon; (ii) increased or decreased antioxidant function, as observed in the kidney; (iii) decreased antioxidant function, such as in the lungs and (iv) no changes, such as in the small intestine, spleen, pancreas, heart, liver and stomach. Additionally, SOD may be the antioxidant enzyme most sensitive to combined TT and radon treatment. Collectively, the combined treatment may be the most effective in activating antioxidative functions in the brain and colon. This study provides new insights into the effects of combined TT and radon inhalation.

kn-title=Proton pump rhodopsins for optogenetic manipulation of biological activities and beyond
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Water (H2O), the principal component of living organisms including humans, dissociates into H+ and OH- in aqueous environments, and the resulting H+ concentration determines both cellular pH and the proton motive force (PMF) across cellular membranes. These physicochemical parameters are fundamental regulators of a wide range of biological processes. Optogenetics enables the manipulation of biological and cellular functions using light, typically through the ectopic expression of microbial rhodopsins as photoreceptive proteins in target cells or organs. This review provides a comprehensive overview of optogenetic studies employing H+ pump rhodopsins in diverse biological systems and highlights their growing relevance to neuroscience, cell biology, bioengineering, and therapeutic research. Notably, optical control of H+ concentration allows the precise modulation of neural and non-neural activities in animals and bacteria, highlighting the broad applicability and significant potential of H+ pump rhodopsins for optogenetics. Based on previous and current studies, we discuss how further expansion of the molecular toolkit of H+ pump rhodopsins could enable increasingly fine-tuned manipulation of intracellular pH dynamics and PMF for probing cellular physiology and designing next-generation therapeutic strategies and consider emerging directions that extend beyond classical optogenetics toward the optical control of bioenergetic and chemical processes.

kn-title=Association of initial interface formation time with CD34+ collection efficiency in continuous mononuclear cell collection: A retrospective study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Factors influencing CD34+ cell collection efficiency (CE) during peripheral blood stem cell harvesting have been investigated; however, the impact of procedural management remains unclear. In continuous mononuclear cell (CMNC) collection, a stable cell–plasma interface (IF) is formed through channel priming, initial IF establishment, and mononuclear cell (MNC) collection. Although IF instability is known to impair CE, the adequacy of initial IF formation has not been examined as an independent factor. Therefore, we focused on the time required for initial IF formation and its association with CE.
Methods: We retrospectively analyzed 291 Spectra Optia CMNC procedures (52 autologous and 239 allogeneic) performed between 2016 and 2025. Initial interface formation time (IFT) was defined as the interval from the start of the procedure to transition to MNC collection. CE2 was defined as the ratio of collected CD34+ cells to the product of pre-apheresis peripheral blood CD34+ cell concentration and processed blood volume.
Results: CE2 was lower in autologous than in allogeneic collections (41.3% vs. 59.2%) and was associated with longer IFT (median, 18 vs. 15 min). CE2 correlated with white blood cell count (r = −0.24), hematocrit (r = 0.36), and IFT (r = −0.23; all p < 0.001). In multivariable analysis, these factors remained independently associated with CE2, and IFT was inversely correlated with hematocrit (r = −0.44, p < 0.001).
Conclusion: IFT is independently associated with CE2 and provides insight into the early dynamics of IF formation during leukapheresis, highlighting an underexplored procedural aspect of CE.

kn-title=Upregulation of the Outer Membrane Protein OmpV and Its Role in Polymyxin B Stress Adaptation in Vibrio mimicus
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=OmpV is an outer membrane protein found in a variety of Gram-negative bacteria. In this study, we demonstrated that V. mimicus strain CS-66, isolated from a patient with diarrhea, was resistant to polymyxin B (PL-B) and colistin (CL) but susceptible to chloramphenicol and ciprofloxacin. When strain CS-66 was cultured in Luria–Bertani broth containing a sub-minimal inhibitory concentration of each antibiotic used for the susceptibility tests, ompV expression as assayed by reverse transcription-qPCR, significantly increased regardless of the antibiotic tested. In contrast, cell aggregation during the early log phase was observed only when the strain was grown in the broth supplemented with PL-B or CL. A space-filling model of V. mimicus OmpV was generated. The model showed that, although OmpV adopted a β-barrel conformation, it had closed top and bottom ends and possessed a lateral cavity. Structural analysis further indicated that the interior of this lateral cavity was negatively charged and sufficiently large to accommodate PL-B. These results suggest that V. mimicus may adapt to PL-B stress through physical sequestration within the negatively charged cavity of OmpV.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We investigate the thermodynamic, scattering, and flow properties of pullulan, a flexible non-ionic polysaccharide in aqueous solution, focusing on semidilute and concentrated solutions. We review dilute solution data for the intrinsic viscosity and radius of gyration and hydrodynamic radius of aqueous pullulan and find the Kuhn length and thermal blob size, below which the polymer chain is nearly ideal, to be 3 nm and 20 nm, respectively. We establish the scaling laws for static correlation length, specific viscosity, osmotic pressure, and osmotic compressibility across dilute, semidilute, and concentrated regions, finding that the scaling exponents align well with theoretical predictions but the crossover concentrations obtained from different methods are not consistent. The ratio between the osmotic and Ornstein–Zernike correlation lengths ξΠ/ξOZ is approximately 2.5 for aqueous solutions, similar to that observed in polystyrene in a theta solvent. This similarity may arise because the crossover concentration between the semidilute and concentrated regions c∗∗ is close to the overlap concentration c∗.

kn-title=Effects of Transplanting Date and Photoperiod on Flowering of Everbearing Strawberries
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Everbearing strawberries have the potential to produce fruit year-round if transplanted early. However, temperature and plant physiological status limit the continuous flowering. Herein, we aimed to investigate whether promoting flowering through long-day phototreatment enables earlier transplanting. The interaction between transplanting date and photoperiod in two everbearing strawberry cultivars was examined. In the 04 cultivar, which exhibited strong everbearing characteristics, rapid and continuous flowering occurred largely independent of long-day treatment, and early transplanting alone increased inflorescence number and early yield. However, excessive flowering was associated with reduced average fruit weight, soluble solid concentration, and firmness. Conversely, in Yotsuboshi, a cultivar with weak everbearing characteristics, earlier transplanting combined with extended photoperiods advanced the emergence of the first and second inflorescences. However, gains in total early yield were small, and the average fruit weight decreased compared with that in the control, indicating physiological stress. Across the cultivars, earlier inflorescence emergence was negatively correlated with days to flowering and positively associated with cumulative yield. For practical applications, cultivars with strong everbearing characteristics can be managed with early transplanting and minimal long-day supplementation to ensure early production. In contrast, cultivars with weak everbearing characteristics require extended photoperiods following early transplanting along with stress-mitigation strategies to maintain fruit size and quality.

kn-title=Development of a novel histidine-rich glycoprotein measurement system as a biomarker for sepsis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The plasma histidine-rich glycoprotein concentration is a marker of sepsis severity. In this study, we generated selective and specific monoclonal antibodies against histidine-rich glycoprotein for use in a prototype enzyme-linked immunosorbent assay-based in vitro diagnostic system. First, we investigated the properties of monoclonal antibodies produced by 21 hybridomas that we developed using immunized mice, and we identified monoclonal antibodies 69-1A and 75-2D to be the most suitable combination for use in the sandwich enzyme-linked immunosorbent assay. Wild-type histidine-rich glycoprotein (Form-1, 75 kDa) with a proline residue at amino acid position 204 is the most common isoform of the protein in humans, followed by its variant (Form-2, 77 kDa), which has a serine residue at position 204.
The epitope mapping was examined for the HRG amino acid sequence with 69-1A and 75-2D mAbs to achieve the identification of respective specific binding domains, though the other kinds of mAbs showed considerably complex domains. The identified epitopes recognized by 69-1A and 75-2D monoclonal antibodies did not span position 204. Furthermore, immunoprecipitation-immunoblotting analysis showed that the 69-1A and 75-2D monoclonal antibodies could bind to both Form-1 and Form-2 in human plasma samples. Thus, these two new antibodies can be used to clearly detect both forms of histidine-rich glycoproteins in human plasma samples. In our analysis of clinical samples by enzyme-linked immunosorbent assays using various combinations of our newly synthesized antibodies, we found that the histidine-rich glycoprotein concentration was significantly lower in plasma samples from septic patients than in those from healthy volunteers (p < 0.01). Thus, our novel analysis system using the new antibodies is expected to be a useful tool for sepsis research, and it may be adapted as an in vitro diagnostic tool for many other kinds of diseases in the future.

kn-title=Students’ perceptions of an electronic one-minute paper in a radiography training programme: An exploratory cross-sectional questionnaire study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: Formative assessment can support health professions education; however, reports on electronic 1-min papers as classroom feedback and engagement tools in radiography programmes remain limited. This study explored radiography students’ perceptions of an electronic 1-min paper, focusing on in-class reflection, ease of asking questions, and instructor feedback.
Methods: An electronic 1-min paper was used in a radiotherapy course across 45 class sessions in the 2024 academic year for third-year students enrolled in a 4-year radiography programme. Each 90-min class comprised a 60-min lecture, 10-min completion of the paper, and 20-min instructor feedback. After the course, a de-identified online questionnaire was administered. Eleven 5-point Likert-scale items were analysed using descriptive statistics and Spearman's rank correlations. Free-text responses were analysed using inductive qualitative content analysis.
Results: Of the 77 eligible students, 74 responded (96.1%). Ease of use received the highest rating (mean, 4.76; standard deviation [SD], 0.52), followed by ease of asking questions (mean, 4.32), question resolution (mean, 4.16), and usefulness of instructor feedback (mean, 4.08). Motivation to review after class was lowest (mean, 3.04; SD, 1.16). Active participation showed a strong positive association with in-class concentration (rs = 0.815; P < 0.001). Free-text responses indicated reflection and improved understanding, anonymous sharing of questions, active listening and concentration, and suggestions for improvement.
Conclusion: The electronic 1-min paper was widely accepted and perceived to support in-class reflection, question expression, and immediate feedback. However, students’ perceptions of its influence on out-of-class review motivation were limited. The findings indicate perceived value and engagement rather than demonstrated educational effectiveness.
Implications for practice: Electronic 1-min papers may help instructors identify students’ questions and respond during class, providing a practical approach to in-class feedback.

kn-title=Atomic imaging for hydrogen and boron aggregates in boron-doped diamond by spectro-photoelectron holography
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The electrical properties of diamond are modulated by impurity doping. Isolated substitutional boron atoms introduce holes; however, the fraction of electrically inactive boron atoms increases at higher doping concentrations. This has been attributed to boron aggregation and hydrogen passivation, although their structural identification based on atomic arrangement has yet to be experimentally verified. Here we show the origin of multiple chemical states in homoepitaxially grown boron-doped diamond thin films by analyzing the atomic environment of boron using spectro-photoelectron holography. Our analysis identifies boron dimers and boron-hydrogen complexes, with hydrogen occupying different atomic sites that give rise to distinct chemical shifts. These results suggest that hydrogen incorporation during growth leads to passivation of boron acceptors. We demonstrate that photoelectron holography serves as a promising tool for imaging hydrogen as well as determining the atomic sites of dopants.

kn-title=Asthma-like bronchodilator responsiveness in patients with neuronal intranuclear inclusion disease
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative condition characterized by the presence of intranuclear inclusions in neuronal and visceral cells. Patients with NIID can present respiratory symptoms; however, data on pulmonary functions in NIID are lacking. This study investigated the respiratory conditions in NIID patients diagnosed with histopathological and genetic studies. We conducted two spirometries before and after administrating the bronchodilator in NIID patients with asthmatic histories or symptoms. We statistically compared pre- and post-measured values including forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). Before two spirometries, we also measured fractional concentration of exhaled nitric oxide (FeNO), if possible. Of the 51finally enrolled patients, 17 (33.3%, 95% CI 20.8% to 47.9%) patients had asthmatic histories or symptoms, and 14 patients received two spirometries. After administrating the bronchodilator, FEV1 and PEF significantly increased by 150 mL (6.01%, p = 0.002) and 260 mL/s (6.72%, p = 0.017), respectively. The median (interquartile range) of FeNO measured in nine patients was 15 (10–21) ppb. Patients with NIID have airflow reversibility like asthma. This condition appears to be less associated with airway inflammation and may be related to autonomic dysfunction.

kn-abstract=The red swamp crayfish Procambarus clarkii (Girard, 1852) is a globally invasive species that poses serious threats to native biodiversity and ecosystem functioning. In South Korea, established populations of P. clarkii have been documented from the Jiseokcheon River in the Yeongsangang River basin since 2018; however, information on its current nationwide distribution remains limited. We conducted environmental DNA (eDNA) surveys at 19 sites across 11 river systems in South Korea, including sites with no prior distributional records, to evaluate the current distribution and potential range expansion of P. clarkii. Water samples collected during July-August 2024 were analyzed using quantitative real-time PCR (qPCR) with two species-specific primer-probe sets targeting the mitochondrial COI gene. Procambarus clarkii eDNA was detected at three sites in the Yeongsangang River basin, whereas no eDNA was detected in the other surveyed river systems. Notably, P. clarkii eDNA was not detected at a site in the Mangyeonggang River system despite previous reports of individuals and eDNA data sampled there, indicating a possible local population decline or very low abundance. By contrast, detections within the Yeongsangang River basin, together with elevated eDNA concentrations at some sites, are consistent with localized upstream expansion and increased local abundance. The concordant results from the two primer-probe sets, together with Sterivex-based on-site filtration, support the reliability of the applied eDNA framework. These findings identify the Yeongsangang River basin as the current primary focus of the P. clarkii invasion in South Korea, with evidence consistent with localized upstream expansion and increasing abundance, and provide baseline data for early detection and long-term monitoring, as well as for developing management strategies.

kn-title=Staphylococcus aureus δ-Toxin Induces Ca2+ Influx-Independent Degranulation of Murine Cultured Mast Cells
en-subtitle=

en-abstract=
kn-abstract=Cutaneous colonization with Staphylococcus aureus (SA) is frequently observed in patients with atopic dermatitis. SA produces a wide variety of bacterial toxins, among which δ-toxin was found to induce degranulation of mast cells. Degranulation of mast cells could enhance bacterial clearance and protection from future SA infection but lead to exacerbation of atopic dermatitis. Because it remains to be determined how δ-toxin triggers degranulation, we investigated δ-toxin-induced changes in murine bone marrow-derived cultured mast cells in this study. We found that δ-toxin-induced degranulation could be classified into two phases, an early Ca2+-independent and a late Ca2+-dependent phase. Recent studies suggest that NOD-like receptor family, pyrin domain containing 3 is involved in the degranulation of mast cells, raising a possibility that leakage of K+ induced by δ-toxin is involved in the Ca2+-independent phase. However, Ca2+-independent degranulation remains unchanged although Ca2+-influx and degranulation induced by δ-toxin were significantly suppressed in the presence of high concentrations of K+. Because actin depolymerization was reported to induce degranulation in the absence of Ca2+ in the permeabilized rat peritoneal mast cells, a slow but steady decrease in the amount of filamentous actin observed here may be involved in Ca2+-independent degranulation induced by δ-toxin. Although Mas-related G protein-coupled receptor (MRGPR) X2 in humans and Mrgprb2 in mice are regarded as the receptors responsible for immunoglobulin E-independent degranulation, δ-toxin-induced degranulation remained unchanged in Mrgprb2−/− mast cells. Our findings pave the way for identification of the target receptors of δ-toxin.

kn-title=Overexpression of diglucosyldiacylglycerol synthase leads to daptomycin resistance in Bacillus subtilis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The lipopeptide antibiotic daptomycin exhibits bactericidal activity against Gram-positive bacteria by forming a complex with phosphatidylglycerol (PG) and lipid II in the cell membrane, causing membrane perforation. With the emergence of daptomycin-resistant bacteria, understanding the mechanisms of bacterial resistance to daptomycin has gained great importance. In this study, we aimed to identify the genetic factors contributing to daptomycin resistance in Bacillus subtilis, a model Gram-positive bacterium. Our findings demonstrated that overexpression of ugtP, which encodes diglucosyldiacylglycerol synthase, induces daptomycin resistance in B. subtilis. Specifically, overexpression of ugtP resulted in increased levels of diglucosyldiacylglycerol (Glc2DAG) and decreased levels of acidic phospholipids cardiolipin and PG, as well as the basic phospholipid lysylphosphatidylglycerol. However, ugtP overexpression did not alter the cell surface charge and the susceptibility to the cationic antimicrobial peptide nisin or the cationic surfactant hexadecyltrimethylammonium bromide. Furthermore, by serial passaging in the presence of daptomycin, we obtained daptomycin-resistant mutants carrying ugtP mutations. These mutants showed increased levels of Glc2DAG and a >4-fold increase in the minimum inhibitory concentration of daptomycin. These results suggest that increased Glc2DAG levels, driven by ugtP overexpression, modify the phospholipid composition and confer daptomycin resistance in B. subtilis without altering the cell surface charge of the bacteria.

kn-title=Formation of Nonspherical Cellulose Acetate Microparticles under Microflow
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Nonspherical particles have gained significant interest owing to their unique shapes and large specific surface areas, making them suitable for a wide range of applications, such as drug delivery, catalysis, and adsorption. However, conventional methods for preparing nonspherical particles face certain limitations. In this study, we propose a simple method for fabricating nonspherical cellulose acetate (CA) microparticles using a microfluidic device in which droplets undergo rapid diffusion in a continuous aqueous phase. The influence of variations in the flow rate ratio and continuous phase composition on the dimensionless Péclet number (Pe) within the droplet and shape of the resultant particles is investigated. Pe is critical, because it indicates the balance between polymer diffusion and droplet shrinkage dynamics. Our findings reveal that increasing the flow rate ratio and reducing the methyl acetate concentration in the continuous phase lead to faster droplet shrinkage and an increased Pe. A high Pe (>100) suggests that the reduction of the droplet interface predominates over polymer diffusion, resulting in the formation of a viscous layer near the droplet surface, which subsequently leads to nonspherical particle shapes (such as bowl-like or biconcave structures). In situ time-lapse observations of droplets from the top and side of a microchannel reveal that the formation of a viscous layer near the droplet surface and the deformation of the droplet, influenced by the z-axis location of the droplets during particle formation, ultimately determine the final particle shape. Based on these observations, a linear correlation between the initial conditions, i.e., the Pe and z-axis location at which the viscous layer formed, is established, enabling the prediction of the particle structure. In summary, the present study enhances the understanding of shape control in microfluidic particle formation and offers a novel guideline for the fabrication of spherical and nonspherical particles.

kn-title=Solution Structure and Counterion Condensation of Carboxymethyl Cellulose in Organic Solvents
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We report scattering (SANS and SAXS) and electrical conductivity data for aqueous and organic solutions of carboxymethyl cellulose with tetrabutylammonium counterions. For SANS in deuterated solvents, the contrast is heavily dominated by the hydrogen-rich counterions, while for SAXS the polymer backbone has a more significant contribution to the scattering signal. The correlation length calculated from the SAXS measurements follows a scaling law of ξ ∝ c–1/2, while that measured by SANS displays a weaker exponent at higher concentrations for solvents of high dielectric constants. These results indicate a decoupling in the characteristic length scales of fluctuations of the polymer backbone and counterions at high polyelectrolyte concentrations. The stretching parameter calculated from the correlation length indicates a highly stretched local conformation for TBACMC in water and several high dielectric constant solvents, consistent with the semiflexible nature of the cellulose backbone. In solvents of lower dielectric permittivity, the chains display a higher degree of local coiling. Combining electrical conductivity and scattering data, we find that the fraction of monomers bearing a dissociated charge is nearly independent of concentration and approximately proportional to the reciprocal of the Bjerrum length of the solvent, as expected by the Oosawa-Manning model.

kn-title=Effects of secondary hydrothermal fluids on gallium distribution and coordination in hot springs silica using Ga K-edge XANES
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Gallium (Ga), a critical element in the electronics industry, is enriched in hot spring silica deposits (sinter) at concentrations comparable to, and in some cases greater than, bauxite, coal, and sphalerite deposits from which it is currently extracted. Focusing on well characterized Holocene and Pleistocene New Zealand sinters, we utilize synchrotron-X-ray fluorescence (sXRF) and Ga K-edge X-ray absorption near edge structure (XANES) spectroscopy to examine the spatial distribution of Ga as well as its changing coordination number. Ga+3 is the only observed oxidation state in the analyzed sinters. Gallium is predominantly found in tetrahedral coordination in sinter deposited from alkali chloride fluids, with analyses best matching Ga-aluminosilicate standards. However, Ga coordination is octahedral in sinter samples that have undergone alteration by acidic fluids/gases, associated with a change in hydrology from alkali-chloride to acid-sulfate fluid conditions. High Ga concentrations are found associated with both these coordination environments, with a heterogeneous distribution. Octahedral Ga is observed both as particles and in larger regions affected by Fe-rich fluid overprinting. The combined use of sXRF and XANES demonstrates an ability to fingerprint diagenesis and alteration in these complex geothermal settings where tetrahedral and octahedral Ga co-exist. The transition from tetrahedral to octahedral Ga also appears to mimic the inferred natural process forming lateritic bauxite deposits, where remobilized tetrahedral Ga is reconcentrated and adsorbed to oxides. A similar process may occur for sinter Ga enrichment, whereby introduced Ga in acidic conditions is adsorbed to oxide phases as the Fe-rich secondary fluids infiltrate porous sinter material.

kn-title=Interfacial Bond Strength of Resin Cement to Polyetheretherketone (PEEK) Using Experimental Primers Doping Multifunctional Methacrylate and Acrylate Monomers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Polyetheretherketone (PEEK) is a high-performance thermoplastic polymer with low surface energy, chemical inertness, and a highly crystalline structure, which limit durable adhesion to resin-based materials and require improved bonding strategies. This in vitro study evaluated the effect of incorporating multifunctional methacrylate (TMPTMA) and acrylate monomers (A-TMPT and A-DPH) into an experimental primer on the 24 h shear bond strength (SBS) of resin cement to PEEK (n = 6 per group). Experimental primers were prepared by adding varying amounts (100–500 µL) of each multifunctional monomer to a UDMA/MMA-based primer, and SBS was measured after cementation with a dual-cure resin cement. TMPTMA-containing primers produced median SBS values of approximately 10–12 MPa, while acrylate-based primers showed slightly higher values, particularly at higher concentrations, reaching up to ~15.8 MPa; however, no statistically significant improvement over the control group was observed (p > 0.05). Failure modes were predominantly mixed across all conditions. These findings indicate that multifunctional monomers, despite their potential to enhance cross-link density and wetting, do not substantially overcome the intrinsic adhesion-resistant nature of polished PEEK. The results underscore that monomer modification alone is insufficient and that effective adhesion to PEEK likely requires integrated strategies combining chemical activation with mechanical surface conditioning.

kn-title=HIP COMPASS®: A Mechanical Intraoperative Navigation Guide Associated with Improved Revision-Free Implant Survivorship after Ceramic-on-Ceramic Total Hip Arthroplasty at Minimum 10-Year Follow-up
en-subtitle=

kn-abstract=HIP COMPASS® has demonstrated improved accuracy in intraoperative support for the acetabular component insertion angle. We assessed long-term revision-free implant survivorship following total hip arthroplasty (THA) using HIP COMPASS, with ≥10 years of follow-up. We retrospectively analyzed 210 hips of 186 patients who underwent cementless THA with ceramic-on-ceramic bearing couples, with or without HIP COMPASS. The mean follow-up duration was 10.8 years in the HIp COMPASS group and 12.7 years in the control group. Overall, 86.0% and 78.2% of cups were placed within Lewinnek’s safe zone with and without HIP COMPASS, respectively. Variability in radiographic inclination and anteversion was greater in the control group than in the HIP COMPASS group. Dislocation rates were 3.2% in the control group and 1.2% in the HIP COMPASS group, with no significant difference between groups. The control group had a significantly higher revision rate than the HIP COMPASS group (7.3% vs. 1.2%). Use of HIP COMPASS was associated with improved long-term revision-free implant survivorship over ≥ 10 years and more consistent acetabular component positioning at an appropriate insertion angle, which may contribute to stable initial fixation.

kn-title=Hochuekkito attenuates anxiety-like behavior associated with pulmonary inflammation induced by intratracheal lipopolysaccharides in mice
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: We have previously demonstrated that intratracheal lipopolysaccharide (LPS) injection induces significant pulmonary inflammation accompanied by hippocampal microglial activation, indicative of neuroinflammation. Hochuekkito (HET) is a traditional Japanese herbal medicine used to treat various conditions, including mental disorders and physical weakness. We have previously reported that HET ameliorates anxiety-like behaviors induced by intraperitoneal LPS injections in mice. However, its anxiolytic effects on anxiety-like behaviors due to pulmonary inflammation remain poorly understood. Therefore, in the present study, we aimed to investigate the effects of HET on anxiety-like behaviors induced by intratracheal LPS injection in mice.
Methods: Mice received HET (1.0 g/kg) once daily for 2 weeks through oral gavage prior to LPS treatment. The light-dark box test was conducted 24 h following LPS injection to assess anxiety-like behaviors. Diazepam, a clinically used anxiolytic, served as a positive control. The lung wet-to-dry weight ratio was determined, and the concentrations of interleukin-6 (IL-6) in the lungs and serum were assessed.
Results: Repeated administration of HET prevented the development of anxiety-like behaviors and reduced serum IL-6 concentrations and hippocampal Il6 mRNA expression levels in LPS-treated mice. Diazepam failed to exert significant effects in LPS-treated mice, whereas HET remained effective under inflammatory conditions. Moreover, LPS injections significantly increased the number of Iba-1-immunoreactive microglial cells in the CA1 region of the hippocampus, whereas this effect was suppressed by treatment with HET. In the bronchoalveolar lavage fluid (BALF), the LPS-induced increase in white blood cell count was significantly reduced by treatment with HET. Furthermore, HET alleviated LPS-induced pulmonary inflammation, as evidenced by decreased lung wet-to-dry weight ratios.
Conclusion: This study suggests that inflammation induced by intratracheal LPS injection contributes to anxiety-like behaviors in mice and that IL-6 may play a key role in linking peripheral inflammation to neuroinflammatory responses. The anxiolytic effects of HET appear to be associated, at least in part, with the suppression of IL-6 elevation in both the periphery and the hippocampus, along with attenuation of microglial activation. Our findings suggest that HET may serve as a potential therapeutic agent for anxiety-like behaviors associated with pulmonary inflammation.

kn-title=Adolescent envy-like social comparison stress induces HPA axis hypoactivity and anxiety in female mice: implications for somatic symptom disorder
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Adolescence is a critical developmental window marked by heightened neuroplasticity and maturation of the stress response system, conferring vulnerability to psychosocial stress. Chronic stress during this period increases the risk of anxiety and depressive disorders and may contribute to somatic symptom disorder (SSD), which is characterized by medically unexplained physical complaints and shows a striking female predominance. The impact of envy-like stress arising from social comparison, a pervasive psychosocial factor in modern society, remains poorly understood. Male and female C57BL/6N mice were exposed to chronic envy-like stress from postnatal day (P)21 to P52 by housing them adjacent to enriched cages, while control mice were housed without such exposure. From P52 onward, mice underwent behavioral testing of anxiety-like behavior, exploratory activity, social interaction, spatial working memory, motor coordination, nociception, and depression-like behavior. Serum corticosterone and adrenocorticotropic hormone (ACTH) concentrations were measured to assess hypothalamic–pituitary–adrenal (HPA) axis function. Envy-like stress induced sex-specific phenotypes. Male mice exhibited hyperactivity, reduced social interaction, and impaired spatial working memory. In contrast, female mice displayed robust increases in anxiety-like behavior, impaired motor coordination, and significant reductions in basal corticosterone and ACTH levels. Chronic envy-like stress during adolescence elicits distinct, sex-dependent behavioral and endocrine alterations. The phenotype observed in female mice—characterized by heightened anxiety and lower basal HPA axis hormone levels—shares some biological features with clinical observations in SSD. This model may serve as a starting point for elucidating the mechanisms linking psychosocial stress and somatic symptoms in a sex-dependent manner.

kn-title=Minimal Association Between Immunoglobulin A Coating and Gut Microbiota Alterations Induced by High-Fat Diets with Distinct Fatty Acid Compositions
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=High-fat diets (HFDs) containing dietary fats with different fatty acid (FA) compositions alter gut microbiota composition in a fat-source-dependent manner. Immunoglobulin A (IgA) and unabsorbed lipids in the distal gut are potential regulators of the gut microbiota. However, their roles in mediating gut microbiota alterations induced by dietary fats with different FA compositions remain unclear. This study aims to examine the associations of these two factors with fat-source-dependent gut microbiota alterations. BALB/c mice were fed a normal diet, a high-lard diet, a high-olive oil diet, or a high-soybean oil diet for 27 weeks. Fecal samples were collected to assess microbiota composition, the IgA coating index (ICI)—which quantifies the extent of IgA coating on gut microbiota—and fecal fatty acid concentrations. At the phylum level, the concentration of fecal total long-chain fatty acids (LCFAs) was positively correlated with the relative abundance (RA) of Bacillota and negatively correlated with that of Bacteroidota. In addition, a trend toward a positive association between the RA and the ICI was observed for Bacillota but not for Bacteroidota. At the genus level, the RAs of 12 taxa were positively correlated with fecal LCFA concentrations, whereas those of 6 taxa were negatively correlated. Although the RAs of most taxa appeared to be influenced by unabsorbed lipids and additional factors, only four Bacillota genera exhibited a positive correlation between the RA and the ICI. Our observations suggest that IgA coating of the gut microbiota may have a minimal association with fat-source-specific alterations in gut microbiota composition during HFD intake.

kn-title=Highly sensitive detection of cancer cells using a voltage-tuned terahertz chemical microscope
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Terahertz chemical microscopy (TCM) is a promising label-free technique for detecting biochemical interactions by monitoring changes in terahertz (THz) wave emission from semiconductor sensing plates. However, quantitative biological detection has been hindered by large plate-to-plate variations originating from uncontrolled depletion-layer electric fields formed during fabrication. These variations shift the response curve of THz amplitude and reduce reproducibility and sensitivity. Here, we introduce a voltage-tuned sensing plate that allows direct control of the depletion-layer electric field by applying a bias voltage to the Si layer of the sensing plate. This enables deliberate adjustment of surface potential and alignment of the THz response curve to the region of highest gain. Using lung adenocarcinoma cells (PC9) captured via AE1/AE3 antibodies targeting specific cell-surface antigens, we demonstrate that voltage tuning enhances detection sensitivity by up to 50-fold and restores linearity between THz amplitude and the logarithm of cell concentration, even in plates with negligible response at 0 V. These findings establish voltage control as a simple, universally applicable strategy to stabilize TCM performance, reduce fabrication-induced variability, and improve analytical sensitivity for biosensing and materials-analysis applications.

kn-title=Linking the Spin Transition of Ferric Iron in δ‐(Al,Fe)OOH to Water Storage in the Lower Mantle
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=As the most massive geochemical reservoir, the lower mantle affects the Earth's budget of volatile elements, including hydrogen or H2O. The properties of minerals in the lower mantle are further affected by changes in the electronic configurations of iron cations, that is, by spin transitions. The feedback between spin transitions and potential storage of H2O in solid hydrous phases in the lower mantle, however, remains unexplored. By combining high-pressure nuclear resonant inelastic X-ray scattering and high-pressure high-temperature X-ray diffraction experiments, we constrained the thermal equation of state of δ-(Al,Fe)OOH, a member of the phase H solid solution. Based on the derived thermal equation of state of δ-(Al,Fe)OOH and the underlying thermodynamic model, we calculate the excess Gibbs free energy that arises from the spin transition of ferric iron in this compound and evaluate the effect on phase equilibria. The results of our analysis show that the spin transition of ferric iron in phase H may significantly reduce the thermodynamic activity and hence the concentration of H2O in a coexisting hydrous melt. As a consequence, nominally anhydrous minerals of the lower mantle may become dehydrated in the presence of phase H. Our analysis further suggests that, under certain conditions, the spin transition may expand the thermal stability of Fe3+-bearing phase H and create a geochemical link between the storage of H2O in phase H and ferric iron in the lower mantle.

kn-title=Effect of caffeine on life-history traits on the red flour beetle, Tribolium castaneum (Coleoptera: Tenebrionidae)
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Nowadays, addressing insect pest infestation effectively requires environmentally sound and sustainable pest control methods that minimize environmental pollution. Caffeine (1, 3, 7-trimethylxanthine), a plant-derived secondary metabolite, has insecticidal, hormonal and antifeedant properties, making it a promising and more sustainable alternative for pest management. In this study, the red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), a serious stored pest, was used to investigate the effects of different caffeine concentrations on life-history traits. We applied two delivery methods: 1) oral exposure through a caffeine–sucrose solution for adults, and 2) dietary incorporation of caffeine powder mixed with wheat flour and brewer’s yeast for adults and their larvae. To evaluate the effect of caffeine on life-history traits, adult longevity, pupation rate, larval period, pupal weight, adult body size and food consumption were examined. Results revealed higher caffeine concentrations (> 1%) significantly reduced longevity, delayed pupation, decreased pupal number, pupal weight and adult body size in both males and females. Lower caffeine concentration (0.01%) increased pupal number but resulted in lower offspring quality, such as smaller pupal weight and adult size. The results show that caffeine has negative effects on life-history traits of T. castaneum, suggesting its potential use as a natural pesticide in caffeine-based sustainable pest-management programs and integrated pest management (IPM).

kn-title=Comparative study of Ni–CeO2 catalysts prepared by impregnation and coprecipitation for CO2 methanation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study explores how synthesis methods affect the structure and CO2 methanation performance of Ni–CeO2 catalysts prepared by coprecipitation and impregnation under identical conditions. Coprecipitation generated particles below 100 nm with uniform elemental distribution, together with large bulk-like particles exhibiting locally concentrated Ni species, attributed to differences in hydroxide solubility. Impregnation, by contrast, produced very large particles (> 500 nm) with smaller particles attached, while maintaining relatively homogeneous elemental distribution. Coprecipitated catalysts showed slightly higher surface area and oxygen vacancy concentration, resulting in higher apparent turnover frequencies (TOFapp) below 300 °C due to enhanced CO2 adsorption and high Ni site density. However, at temperatures above 350 °C, impregnated catalysts displayed higher CH4 selectivity and TOFapp, indicating reduced kinetic limitations and more efficient active-site utilization. These results provide insights for rational design of efficient CO2 methanation catalysts.

kn-title=Reversible Droplet Bridging and Tunable Viscoelasticity in Emulsions Using Biocompatible PLA-b-PEO-b-PLA Telechelic Block Copolymers: Implications for Injectable Emulsion Gels
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Telechelic polymers are known to form reversible networks through end-group association; however, their application as structuring agents in emulsion-based soft materials remains underexplored. Herein, we systematically investigate the biocompatible amphiphilic triblock copolymer poly(d,l-lactic acid)-block-poly(ethylene oxide)-block-poly(d,l-lactic acid)(PLA-b-PEO-b-PLA) as a rheology modifier in toluene-in-water model emulsions. Owing to the selective adsorption of PLA end blocks at the oil–water interface and the solvation of the PEO midblock in the aqueous phase, this polymer is expected to form reversible droplet-bridging networks. During the process, the polymer concentration, molecular weight of the mid and end blocks, and the dispersed phase volume fraction were adjusted, and the factors governing network formation were elucidated using oscillatory rheology and stress-relaxation measurements. The results show that anchoring of the PLA end blocks and PEO-mediated bridging predominantly control the strength and dynamic reversibility of the network. Step-strain experiments further reveal that the droplet-bridging interactions can be disrupted under large deformation and partially recover when small-strain conditions are restored, confirming the presence of reversible physical associations. These findings establish a molecular design strategy for biodegradable telechelic copolymers as effective and reprocessable structuring agents in emulsion gels. The shear-responsive, tunable, and reversible nature of the droplet-bridging network makes this material platform particularly suitable for injectable emulsion gels for advanced soft matter and biomedical engineering applications.

kn-title=Feasibility of Comprehensive Genomic Profiling for Biliary Tract Cancer Using Transpapillary Biopsy Samples: A Prospective Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Patients with biliary tract cancer (BTC) often have actionable mutations, and comprehensive genomic profiling (CGP) plays an important role. However, the feasibility of CGP using transpapillary biopsy (TPB) samples remains unclear.
Methods: Thirty patients with suspected BTC based on radiographic imaging were enrolled. Pre-analytical criteria for CGP suitability were based on the OncoGuide NCC Oncopanel System (NCCOP) and FoundationOne CDx (F1CDx). Each patient underwent six biopsies using an endoscopic introducer: five biopsy samples were preserved as formalin-fixed paraffin-embedded (FFPE) samples and one as a fresh frozen (FF) sample. DNA quality indicators were compared between the two groups.
Results: Malignancy was confirmed in 29 patients, and one had a benign biliary stricture. Suitability rate was 31% (9/29) for NCCOP and 3.4% (1/29) for F1CDx. Compared to FFPE samples, FF samples demonstrated significantly higher DNA concentration [ng/μL, interquartile range (IQR)], [0.34 (0.16–0.95) vs. 37.8 (11.6–67.6), p < 0.001] and DNA integrity number (IQR) [7.1 (6.8–7.3) vs. 8.9 (8.3–9), p = 0.021].
Conclusions: Introducer-assisted multipass TPB may increase the rate of obtaining adequate CGP specimens, but its suitability remains limited and strongly panel dependent. Since FF samples have better DNA quality, establishing a system detailing their use is desirable.

kn-title=Sex-related differences in blood concentrations and emergence profiles following total intravenous anesthesia with remimazolam and remifentanil
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Remimazolam is a novel, short-acting benzodiazepine, which is characterized by rapid onset and quick recovery. The clinical efficacy and metabolism of many intravenous anesthetics are known to be influenced by sex; however, the effects of sex on the anesthetic efficacy and metabolism of remimazolam remain unclear. This prospective observational study examined sex-related differences in pharmacokinetics and emergence profiles after total intravenous anesthesia was induced with remimazolam and remifentanil in patients undergoing oral and maxillofacial surgery. Thirty-five American Society of Anesthesiologists Physical Status 1 adults (19 females, 16 males), aged 18–49 years, received standardized dosing based on their actual body weights. Serum remimazolam concentrations were measured at the end of administration and immediately before extubation using high-performance liquid chromatography. Although the emergence time did not differ significantly between the sexes, the mean emergence time of the females was approximately 80 s shorter. Serum remimazolam concentrations were significantly lower in females at both measurement time points (p < 0.001). This may suggest that remimazolam is metabolized more rapidly in women. Although these sex-related pharmacokinetic differences did not affect the time to awakening under combined remimazolam and remifentanil anesthesia, clinicians should be aware of potential sex differences in the pharmacokinetics of remimazolam.

kn-title=Development of Linear Interpolation System for SMK Model Parameters Evaluated from Cellular-Scale Simulation (LISMEC) and its application to BNCT dosimetry
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Boron neutron capture therapy (BNCT) utilizes high linear energy transfer (LET) α-particles and 7Li ions generated through the 10B(n, α)7Li reaction. Precise dosimetry is essential for maximizing therapeutic efficacy while minimizing normal tissue adverse events, considering the microscopic distribution of 10B and cellular structures. Recently, the photon isoeffective dose (DisoE) has been proposed as a more appropriate metric for BNCT treatment planning and can be evaluated using the stochastic microdosimetric kinetic (SMK) model. However, clinical implementation of the SMK model remains challenging due to the difficulty of evaluating its input parameters, which requires computationally intensive radiation transport simulations at the cellular scale. To address this issue, we developed LISMEC (Linear Interpolation System for Stochastic Microdosimetric Kinetic model parameters Evaluated from Cellular-scale simulation), a rapid estimation framework based on precomputed cellular-scale PHITS (Particle and Heavy Ion Transport code System) simulations covering various cell geometries and boron distributions. By applying a linear interpolation algorithm, LISMEC enables the retrieval of SMK model parameters without the need for computationally intensive cellular-scale simulations. The utility of LISMEC, in conjunction with PHITS, was demonstrated through simulations of various irradiation scenarios in reactor-based BNCT. The results showed that DisoE values ranged from 7.4 to 32.7 Gy, even under a fixed macroscopic 10B concentration of 60 ppm. These findings emphasize the importance of incorporating a microscopic distribution of 10B and cellular structures into BNCT treatment planning.

kn-title=Instrument-free quantitative colorimetric analysis using adsorption-band length in a packed silica gel column
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A simple and instrument-free colorimetric method for quantitative analysis is reported, in which analyte concentration is determined by measuring the length of a colored adsorption band formed in a packed silica gel column. The proposed method employs a miniature silica gel column that acts as a signal transducer after it adsorbs the colored compound from a solution during its flow in the column. The length of this band increases proportionally with analyte concentration, which enables quantitative detection via simple distance measurement. A theoretical model was developed to describe the relationship between solute concentration, adsorption behavior, and band propagation along the column. The principle was validated via the detection of both iron ions and enzyme-mediated glutamic acid. For Fe2+ analysis, the o-phenanthroline complexation method shows a level of sensitivity comparable to that of conventional spectrophotometry, which enables an almost quantitative recovery of trace iron in tap water. The limit of detection (LOD) and the limit of quantification (LOQ) were estimated to be 0.20 μM and 0.60 μM for the proposed method and 0.23 μM and 0.70 μM for spectrophotometry, respectively. The approach was further extended to glutamate detection using a cascade reaction involving glutamate oxidase and horseradish peroxidase with N-benzoyl leucomethylene blue as the chromogenic substrate. The LOD and the LOQ of the proposed method were 0.08 and 0.25 μM, and both values are superior to the 0.24 μM and 0.73 μM obtained using a microplate reader. By integrating preconcentration with a distance-based readout, this method provides a simple yet highly sensitive analytical platform and establishes distance as a quantitative signal for colorimetric detection.

kn-title=Determination of picomolar to sub-nanomolar trace metals in seawater using an alternative chelating resin
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this study, we investigated the potential use of a chelating resin that immobilizes an amine with an iminodiacetic acid group (InertSep ME-2) for trace-metal analysis in natural seawater. Seven trace metals (Mn, Fe, Co, Ni, Cu, Zn, and Pb) were quantitatively preconcentrated onto the InertSep ME-2 chelating resin, eluted with nitric acid, and analyzed using high-resolution inductively coupled plasma mass spectrometry. The blank values and detection limits obtained using our method were at the sub-nanomolar level for most trace metals. These blank values were generally comparable to, or lower than, those previously reported for other chelating resins, including NOBIAS Chelate PA-1 and Toyopearl AF-Chelate-650 M. The accuracy and precision of our method were confirmed by analyzing reference seawater samples, and the results for the open-water samples were consistent with those obtained in an independent laboratory. The established preconcentration procedure was successfully applied to determine trace metal concentrations in natural seawater collected from the northwestern Pacific Ocean. Our method, which employs the InertSep ME-2 chelating resin, is sufficiently accurate for studying trace metals in open-ocean water at picomolar- to sub-nanomolar-level concentrations.

kn-title=Impact of Proteinuria on Postoperative Complications Following Colorectal Cancer Surgery
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Colorectal surgery is associated with a high incidence of postoperative complications regardless of the advances in surgical techniques and multidisciplinary treatment. Proteinuria is common in patients with malignancies, but few studies have investigated the association between preoperative proteinuria and patient prognoses, especially postoperative complications. We investigated the impact of proteinuria on patients undergoing colorectal surgery in a single-center, retrospective cohort study of 767 patients who underwent surgical resection for colorectal cancer between January 2016 and December 2022 at the National Hospital Organization Shikoku Cancer Center. Among them, 81 patients with preoperative proteinuria were compared with the control group of 686 patients without proteinuria. Our analyses revealed that the patients with proteinuria had malnutrition with a significantly lower prognostic nutritional index compared to the no-proteinuria control group (p<0.001). The proteinuria group had a significantly advanced tumor stage (p=0.005), experienced more bleeding during the surgery (p=0.002), and required more transfusions (p<0.001). Postoperative complications were significantly more frequent in the proteinuria group (p=0.03), thus demonstrating that proteinuria was independently associated with postoperative complications (p=0.045). Proteinuria in patients undergoing colorectal cancer surgery can therefore be considered a risk factor for postoperative complications.

kn-title=Functional Transport Properties of Human Zinc Transporter 1: Kinetics and pH-Dependency
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Intracellular zinc (Zn2+) homeostasis is essential for physiological and pathological processes and is strictly regulated by Zn2+ transporters. Zinc transporter 1 (ZnT1) is a ubiquitously expressed plasma membrane-localized Zn transporter that exports Zn2+ from the cytoplasm to the extracellular space. However, the functional transport properties regarding kinetics and driving forces of ZnT1 remain debatable. In this study, we established a cell-free proteoliposome assay system and demonstrated that ZnT1 transports Zn2+ with high affinity in pH-dependent and pH-independent manners. The Km and Vmax of pH-dependent Zn2+ transport were 0.40 μM and 15.13 nmol/min/mg protein, and those of pH-independent Zn2+ transport were 0.52 μM and 8.88 nmol/min/mg protein (low concentrations of Zn2+), 3.02 μM and 17.59 nmol/min/mg protein (high concentrations of Zn2+), respectively, suggesting biphasic kinetic components of Zn2+ transport. Even without pH gradient formation, ZnT1 exhibits potent Zn2+ transport activity. In pH dependency, Zn2+ transport activity was higher at an inside pH of 6.0 than at 6.5–7.5 for proteoliposomes, despite the same ΔpH of 0.5–1.5. The Zn2+ transport activity decreased at an outside pH of 8.0, despite an increase in ΔpH. Although previous studies have proposed that ZnT1-mediated Zn2+ transport activity is driven by a calcium (Ca2+) gradient and not by a pH gradient, Ca2+ does not enhance Zn2+ transport activity in the presence or absence of a pH gradient. These results strongly suggest that ZnT1 protein transports Zn2+ optimally at a specific pH and exports excess intracellular Zn2+ even without ΔpH.

en-title=Network Analysis of Interregional Information Exchange: A Study in the Takahashi River Basin Area
kn-title=地域間での情報交流に関するネットワーク分析:高梁川流域圏での調査による
en-subtitle=
kn-subtitle=
en-abstract= This paper conducted network analysis focusing on information exchange among participating entities in the "Takahashi River Basin Economic Growth Strategy Council," operating within Okayama Prefecture's "Takahashi River Basin Core City Area." The Takahashi River Basin Collaborative Core City Area( Takahashi River Basin Area)is a collaborative core city area encompassing ten municipalities located around the Takahashi River in Okayama Prefecture: Niimi City, Takahashi City, Soja City, Hayashima Town, Kurashiki City, Yakage Town, Ibara City, Asakuchi City, Satosho Town, and Kasaoka City. For the network analysis within the Takahashi River Basin Area, projects implemented within the area were classified into eight categories. A questionnaire survey was conducted regarding information exchange among participating entities for each project. Network metrics included calculating centrality indices( degree centrality and betweenness centrality) for each project, along with density, transitivity, and reciprocity. By project type, tourism projects exhibited the densest network structure for information exchange. From a network perspective, tourism projects can be considered the most actively pursued initiative within the Takahashi River Basin area. Furthermore, across all projects, centrality indicators for specific administrative bodies and regional economic organizations, such as chambers of commerce and industry, generally showed high values. This clearly indicates their function as hubs for information exchange and as entities concentrating or dispersing information within the network. Based on the results of network analysis, two recommendations for future regional development in the Takahashi River Basin were proposed from a network perspective. The first is to aim for dense networks across all businesses by sharing the roles of information exchange hubs and information concentration/distribution entities among the entities involved, depending on the business. The second is to aim for a dense network overall by eliminating entities that are not participating at all in the Takahashi River Basin's information exchange network.
kn-abstract= 本稿では,岡山県の「高梁川流域連携中枢都市圏」で2014年から開催されている「高梁川流域経済成長戦略会議」における参加主体間の情報交流についてのネットワーク分析を行った。高梁川流域連携中枢都市圏(高梁川流域圏)とは,岡山県高梁川周辺に位置する現在の新見市,高梁市,総社市,早島町,倉敷市,矢掛町,井原市,浅口市,里庄町,笠岡市の10自治体が参加している連携中枢都市圏である。高梁川流域圏におけるネットワーク分析に際しては,同圏域内で展開されている事業を8つに分類し,それぞれの事業に関する参加主体間の情報交流についてアンケート調査を行った。ネットワーク指標については事業ごとに次数中心性と媒介中心性の中心性指標を,また事業別に密度,推移性,相互性を算出した。事業別にみると,観光事業についての情報交流が最も密なネットワーク構造をしており,ネットワークの視点では観光事業が高梁川流域圏内で最も勢力的に行われている事業といえる。また全事業において特定の行政主体や商工会議所をはじめとする地域経済団体等の中心性指標が全体的に大きな値をとっており,ネットワークにおいて情報交流のハブや情報の集中・分散主体として機能していることが明らかになった。分析結果を踏まえ,ネットワークの視点から高梁川流域圏の今度の地域振興について2点提言した。1つは事業によって情報交流のハブや情報の集中・分散主体を主体間で分担することによって,すべての事業で密なネットワークを築くことを目指すことである。もう1つは高梁川流域圏の情報交流ネットワークに全く参加していない主体をなくすことで,全体的に密なネットワークを目指すことである。

kn-title=Concentration-Dependent Synergistic Interfacial Interactions Between Multifunctional Acrylate and Silane Coupling Agents in an Organic–Inorganic Nanohybrid Material
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Synergistic effects of a multifunctional acrylate and a long-chain silane coupling agent were investigated in an organic–inorganic nanohybrid material. We tested the bond strength of nanohybrid composites treated with experimental primers containing silane coupling agents—3-methacryloxypropyl trimethoxysilane (γ-MPTS) or 8-methacryloxyoctyl trimethoxysilane (8-MOTS)—with or without multifunctional acrylates—trimethylolpropane triacrylate (A-TMPT) or dipentaerythritol hexaacrylate (A-DPH). Shear bond strength was evaluated after 24 h of water storage at 37 °C. Untreated control and silane-only groups exhibited low shear bond strengths (e.g., control: 2.4 ± 2.0 MPa) and failed exclusively at the adhesive interface. While addition of A-TMPT did not significantly improve bond strength, addition of A-DPH produced significantly higher shear bond strengths. Highest strength was achieved with 30% 8-MOTS and A-DPH (22.4 ± 6.1 MPa), followed by 20% γ-MPTS and A-DPH (19.0 ± 7.0 MPa), and A-DPH groups produced cohesive failures. Regardless of the silane used (γ-MPTS or 8-MOTS), incorporating A-DPH in the primer consistently yielded superior bond strengths, indicating a promising strategy for improved adhesion for such nanohybrid systems. These findings provide new insights into optimizing resin–filler interfacial interactions and may contribute to the development of restorative materials with improved long-term clinical durability.

kn-title=Investigation of the cefazolin inoculum effect in blood culture-isolated methicillin-susceptible Staphylococcus aureus strains: A Japanese multicenter study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Cefazolin inoculum effect (CInE) is a microbiological phenomenon where the MIC of cefazolin against methicillin-susceptible Staphylococcus aureus (MSSA) strains increases with higher bacterial volumes.
Method: We retrospectively investigated the prevalence and characteristics of the CInE among MSSA strains isolated from blood cultures at three Japanese hospitals. The collected isolates were screened for blaZ using PCR, and the cefazolin minimum inhibitory concentration (MIC) for the blaZ-positive MSSA isolates was measured at standard and high inoculum volumes. CInE-positive MSSA strains were defined as those with a cefazolin MIC ≥16 μg/mL at 107 CFU/mL and ≤8 μg/mL at 105 CFU/mL. In these blaZ-positive strains, we performed blaZ typing and tested a modified nitrocefin-based rapid examination to detect the CInE.
Results: We collected 329 MSSA strains isolated from blood cultures. Of these, 96 (29.2%) were positive for the blaZ gene, with the following genotypes: type A (15, 15.6%), type B (3, 3.1%), type C (77, 80.2%), type D (0, 0.0%), and non-type (1, 1.0%). Among 96 blaZ-positive MSSA isolates, 11 exhibited the CInE, all of which harbored blaZ type A. The rapid nitrocefin test detected CInE positivity with high sensitivity (100%), specificity (94.1%), and diagnostic accuracy (94.8%).
Conclusion: This study highlighted the low prevalence of CInE-presenting MSSA isolates in Japan. When the cefazolin MIC is ≥1 μg/mL or the penicillin G MIC is ≥0.25 μg/mL, the rapid nitrocefin test may be useful for considering the CInE in patients with high bacterial volume MSSA infections.

kn-title=Streamlined Radiosynthesis of [18F]Fluproxadine (AF78): An Unprotected Guanidine Precursor Enables Efficient One-Step, Automation-Ready Labeling for Clinical Use
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background/Objectives: [18F]Fluproxadine (formerly [18F]AF78) is a PET radiotracer targeting the norepinephrine transporter (NET) with potential applications in cardiac, neurological, and oncological imaging. Its guanidine moiety, while essential for NET binding, presents major radiosynthetic challenges due to high basicity and the harsh deprotection conditions required for protected precursors. Previous methods relied on multistep procedures, strong acids, and complex purification, limiting clinical translation. This study aimed to develop a practical one-step radiosynthesis suitable for routine and automated production. Methods: A direct SN2-type nucleophilic [18F]fluorination was performed using an unprotected guanidine precursor to eliminate deprotection steps. Reaction parameters, including the base system, solvent composition, precursor concentration, and temperature, were optimized under conventional and microwave heating. Radiochemical conversion (RCC) and operational robustness were evaluated, and purification strategies were assessed for automation compatibility. Results: Direct [18F]fluorination using the unprotected precursor reduced the total synthesis time to 60–70 min. Optimal conditions employed a tert-butanol/acetonitrile (4:1) solvent system with K2CO3/Kryptofix222, affording RCC up to 33% under conventional heating. Microwave irradiation further improved efficiency, achieving RCC of up to 64% within 1.5 min at 140 °C. The method showed broad tolerance to variations in the base molar ratio and precursor concentration and enabled isocratic HPLC purification. Conclusions: This one-step radiosynthesis overcomes longstanding challenges in [18F]fluproxadine production by eliminating harsh deprotection and enabling high-yield, automation-ready synthesis, thereby improving clinical feasibility.

kn-title=Extensive urine production in euryhaline red stingray for adaptation to hypoosmotic environments
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Maintaining water balance is a prerequisite for all organisms. Euryhaline elasmobranchs face the severest water-influx potential in fresh water (FW), as they retain high concentrations of urea even in hypotonic environments. To elucidate how they overcome this osmotic challenge, we assessed urine output in conscious euryhaline red stingrays (Hemitrygon akajei). Following acclimation to 5% diluted seawater, the stingrays increased urinary output by 87-fold—the greatest change observed in vertebrates—partly due to 6.8-fold increase in glomerular filtration rate (GFR). In the nephron, expressions of Aquaporin-1 (Aqp1), Aqp3, and Aqp15 were strongly downregulated in FW, indicating that tubular diuresis bridges the gap between GFR and final urine volume. Meanwhile, FW-acclimation upregulated Aqp1 and Aqp4 in the distinct bundle structure, which promotes urea reabsorption. Euryhaline elasmobranchs resolve the huge osmotic challenge of FW by excreting massive amounts of water and retaining osmolytes including urea through coordinated regulation of GFR and Aqp expressions.

kn-title=Comparison of bioavailability of quercetin and its structural analogs in mice
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Flavonoids are thought to provide beneficial effects on health. However, there are still uncertainties regarding their bioavailability. In this study, we investigated the bioavailability of 6 flavonoids, galangin, kaempferol, quercetin, myricetin, fisetin, and luteolin, by oral administration to mice. Analysis of plasma concentrations of free flavonoids after deconjugation by LC-MS/MS revealed that all flavonoids were rapidly absorbed after administration. Among 6 flavonoids, kaempferol and fisetin showed high absorbed amounts in blood plasma. With the LogP value of the two flavonoids as the maximum value, the amount absorbed decreased for both lower and higher LogP values. The results of the tissue distribution of galangin, kaempferol, and quercetin suggested that the order of fastest movement from the stomach to the small intestine was kaempferol > quercetin > galangin. In addition, the amount of kaempferol and quercetin distributed in the liver was greater than that of galangin. These results suggest that the bioavailability of flavonoids varies with the slight structural differences, possibly due to differences in their rapid accessibility to the small intestine that is the primary site of absorption and metabolism within the body.

en-subtitle=

en-abstract=
kn-abstract=Patients with hepatocellular carcinoma (HCC) and extensive peritoneal dissemination generally have a poor prognosis and are often resistant to systemic therapy. We report the case of a 47-year-old woman with HCC and massive peritoneal dissemination who presented with malignant ascites requiring repeated cell-free and concentrated ascites reinfusion therapy and peritoneovenous shunt placement, as well as malignant pleural effusion requiring pleurodesis. Combined immunotherapy with durvalumab/tremelimumab was initiated;however, disease progression was observed after three treatment courses, prompting a switch to lenvatinib therapy. Two months after initiation of lenvatinib, CT imaging demonstrated complete disappearance of arterial enhancement in the primary hepatic lesion, along with reduction in the size of peritoneal dissemination nodules. Thirteen months after switching to lenvatinib (16 months after the initial diagnosis), the alpha-fetoprotein level continued to decrease, and the disease remained stable under treatment. Despite the extremely high tumor burden, lenvatinib achieved disease stabilization and symptomatic improvement.

kn-title=Reactive Carbonyl Species Mediate Isothiocyanate Signaling Pathway in Arabidopsis thaliana Guard Cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Our previous results demonstrated that depletion of glutathione (GSH) rather than elevation of levels of reactive oxygen species (ROS) is highly correlated with the decrease in stomatal aperture induced by isothiocyanates (ITCs), although ROS is considered a key second messenger in stomatal closure, suggesting that another signal component regulates stomatal apertures along with GSH depletion. This study, using Arabidopsis, clarified that reactive carbonyl species (RCS), especially acrolein and 4-hydroxy-(E)-2-nonenal, are determinants of stomatal aperture responses to ITCs. All tested ITCs, allyl isothiocyanate (AITC), sulforaphane (SFN), benzyl isothiocyanate (BITC), and phenethyl isothiocyanate (PEITC), significantly induced stomatal closure, which was inhibited by the RCS scavengers, carnosine and pyridoxamine. The RCS scavengers suppressed ITC-induced depletion of GSH but not elevation of ROS levels. All tested ITCs (AITC, SFN, BITC, and PEITC) increased levels of RCS and non-RCS aldehydes in the epidermal tissues. However, acrolein, 4-hydroxy-(E)-2-nonenal, crotonaldehyde, and (E)-2-pentenal induced stomatal closure at 10 and 100 μM, whereas propionaldehyde, butyraldehyde, and n-pentanal did not at concentrations up to 100 μM. Acrolein and 4-hydroxy-(E)-2-nonenal more effectively induced stomatal closure and GSH depletion than crotonaldehyde and (E)-2-pentenal did. The contents of RCS were more strongly correlated with GSH levels and stomatal closure than with ROS levels. These results suggest that RCS, especially acrolein and 4-hydroxy-(E)-2-nonenal, acts as key regulators of stomatal closure in guard cells in response to ITCs.

kn-title=Sodium butyrate augments the antibacterial activity of tetracycline against clinical isolates of multidrug-resistant Vibrio cholerae
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Antibiotic resistance poses a major challenge in treating Vibrio cholerae infections. One promising method to counter resistance is the co-administration of antibiotics with non-antibiotic adjuvants to enhance their efficacy. This study investigated the combined action of sodium butyrate (SB) and tetracycline on tetracycline-resistant V. cholerae strains.
Results The combined activity of SB and antibiotics was assessed on eight V. cholerae clinical isolates using the Fractional Inhibitory Concentration Index (FICI), with SB-Tetracycline showing strong synergy (FICI: 0.09–0.5). Functional and mechanistic studies, including time-kill kinetics, live/dead staining, SEM-based morphological analysis, and fluorometric assays, demonstrated a synergistic antibacterial effect of SB and Tetracycline. This effect was associated with increased membrane permeability, disruption of membrane integrity, dissipation of the proton motive force, and suppression of efflux activity. These changes collectively led to membrane damage, enhanced intracellular accumulation of Tetracycline, decreased intracellular ATP levels, and ultimately, bacterial cell death. Moreover, GM1-CT ELISA and fluorescence microscopy revealed the synergistic anti-virulence activity of the SB- Tetracycline combination. Finally, the combination of SB and Tetracycline showed enhanced efficacy in animal models compared with monotherapy.
Conclusion: The observed SB-Tetracycline synergy provides a promising therapeutic approach to overcome tetracycline resistance in V. cholerae, offering a potential adjunct strategy for the management of antibiotic-resistant cholera infections.

kn-title=A nuclear CobW/WW-domain factor represses the CO2-concentrating mechanism in the green alga Chlamydomonas reinhardtii
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Microalgae induce a CO2-concentrating mechanism (CCM) to maintain photosynthesis when CO2 is limited. Because this system consumes a substantial portion of photosynthetically generated ATP, its suppression when CO2 levels rise is critical for energy balance, yet the underlying mechanism remains unclear. Here, we identify a nuclear repressor of the CCM in the green alga Chlamydomonas reinhardtii. A pull-down screen for interacting partners of the master activator CCM1/CIA5 revealed an uncharacterized protein that tightly associates with CCM1. This protein, CCM1-binding protein 1 (CBP1), combines a CobW/CobW_C GTP-binding metallochaperone module with a WW-domain characteristic of protein–protein interactions. CBP1 colocalizes and interacts with CCM1 in the nucleus regardless of CO2 conditions. Disruption of CBP1 does not affect growth or CCM induction under CO2 limitation but derepresses 27 of 41 CCM1-dependent low-CO2 inducible genes under high-CO2 conditions. These include the periplasmic and intracellular carbonic anhydrases (CAH1 and LCIB) and inorganic carbon transporters/channels (LCIA, LCI1, BST1, and BST3). Consistently, cbp1 mutants accumulate CAH1 and LCIB proteins and exhibit 40% higher inorganic carbon affinity under high-CO2 conditions; this phenotype is rescued by CBP1 complementation or by acetazolamide treatment. Crucially, cbp1 mutants exhibit significant growth delays under high-CO2 conditions, especially when light is limiting, providing direct evidence that CBP1-mediated repression is essential for energy conservation. Thus, CBP1 prevents unnecessary CCM activity when CO2 is abundant, acting upstream of both transporter/channel and carbonic anhydrase modules. Our findings suggest a regulatory mechanism potentially linking zinc-dependent protein chemistry to CCM gene repression, providing insights into energy-efficient CO2 sensing in aquatic photosynthetic organisms.

kn-title=Pediatric autologous peripheral blood stem cell collection without heparin using a highly concentrated sodium citrate anticoagulant: A retrospective comparison with standard ACD-A
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Heparin combined with sodium citrate has been used in leukocytapheresis for pediatric patients. Since 2022, we have performed leukocytapheresis using a highly concentrated sodium citrate solution (HSC, 5.32%) instead of acid citrate dextrose solution A (ACD-A). We conducted this study to determine whether HSC use reduces run time and the total amount of anticoagulant solution in children.
Study Design and Methods: We retrospectively analyzed data from consecutive autologous peripheral blood stem cell harvests (auto-PBSCHs) between June 2012 and May 2025, including patient characteristics, mobilization methods, protocol used, anticoagulant type, run time, total anticoagulant solution volume, and collection efficiency.
Results: Auto-PBSCH was performed using the mononuclear cell collection (MNC) protocol in 28 procedures and the continuous MNC protocol in 20 procedures. ACD-A was used in 35 procedures and HSC in 13. The run time was significantly shorter (204 [range, 117–302] vs. 157 min [range, 103–227], p = .02) in the HSC group and also confirmed in multivariable regression analysis (coefficient, −55.6; 95% confidence interval, −106.2 to −5.04; p = .03). In a subgroup analysis of cMNC procedures, CD34+ collection efficiency showed a strong negative correlation with the proportion of run time devoted to establishing the initial interface (r = −.73, p = .0003).
Conclusion: Delays in establishing the initial interface can reduce the duration of the effective MNC collection phase and may negatively affect collection efficiency. Careful attention to the initial interface phase is therefore warranted when using HSC.

kn-title=Mycobacterium mageritense-associated refractory cutaneous infection and lymphadenitis in an immunocompetent adult: insights from genomic sequencing
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Nontuberculous mycobacteria are increasingly recognized as causes of chronic and refractory skin and soft tissue infections, even in individuals without immunodeficiency. Among them, Mycobacterium mageritense is a rare, rapidly growing species that can lead to persistent lesions requiring prolonged antimicrobial therapy. Reports of M. mageritense infections involving both the skin and regional lymph nodes are limited, and this case adds new clinical and genomic insights.
Case presentation A 48-year-old previously healthy man presented with a slowly enlarging cutaneous lesion on his lower leg and ipsilateral inguinal lymphadenitis. Empirical antibacterial therapy with β-lactams and macrolides was ineffective. Wound cultures subsequently grew M. mageritense, confirmed by whole-genome sequencing. Several antimicrobial regimens were attempted, and the final successful therapy consisted of oral levofloxacin and minocycline for 4 months, leading to complete clinical resolution. Genomic analysis identified resistance-related genes, including erm(40), aac(2′)-Ib, tet(V), and RbpA, although in vitro minimum inhibitory concentrations showed variable susceptibility. Phylogenetic comparison revealed that the isolate was closely related to previously reported M. mageritense strains from Japan.
Conclusions This case demonstrates that M. mageritense can cause cutaneous infection with secondary lymphadenitis in an immunocompetent host. Accurate species identification using molecular or genomic methods and selection of appropriate combination antibiotic therapy based on susceptibility testing are crucial for successful management of such infections.

kn-title=Bioconversion and Metabolic Fate of the n-1 Polyunsaturated Fatty Acids, 6,9,12,15- Hexadecatetraenoic (C16:4 n-1) and 8,11,14,17- Octadecatetraenoic (C18:4 n-1) Acids, in HepG2 Cells
en-subtitle=

kn-abstract=Fish oil contains not only major fatty acids with double bonds at the n-3, n-6, n-7, and n-9 positions but also those with a double bond at the n-1 position, such as 6,9,12,15-hexadecatetraenoic acid (C16:4 n-1; HDTA). However, intracellular bioconversion and metabolic fate of n-1 polyunsaturated fatty acids (PUFA) remain unclear. Therefore, in this study, we aimed to assess the intracellular bioconversion and metabolic fate of HDTA and its metabolite, 8,11,14,17- octadecatetraenoic acid (C18:4 n-1; ODTA), using HepG2 cells. Based on the results of cell viability and cytotoxicity assays for HDTA and ODTA, the concentration of each fatty acid supplemented in the experiments was set at 10 μM. HepG2 cell culture with HDTA revealed C20:4 n-1 as a new HDTA metabolite, along with previously reported ODTA. Our findings suggest that the HDTA taken up by HepG2 cells undergoes elongation to form ODTA and C20:4 n-1. Following supplementation with HDTA, ODTA, and 5,8,11,14,17-eicosapentaenoic acid (C20:5 n-3; EPA), fatty acids disappeared from the culture medium within 24 h. Notably, the total relative level of HDTA and its metabolites, including ODTA and C20:4 n-1 in HDTA- and ODTA-supplemented cells were significantly lower than the total relative level of EPA and its metabolites, including 7,10,13,16,19-docosapentaenoic acid (C22:5 n-3), C24:6 n-3, and 4,7,10,13,16,19-docosahexaenoic acid (C22:6 n-3) in the EPA-supplemented cells. Except for a portion that was intracellularly elongated, most HDTA was taken up by HepG2 cells and may undergo rapid fatty acid β-oxidation. However, RNA-sequencing and real-time polymerase chain reaction analysis revealed no significant changes in fatty acid β-oxidation–related gene expression levels in HDTA-supplemented cells. Collectively, these results provide novel insights into the intracellular bioconversion mechanisms and metabolic fate of HDTA and ODTA in HepG2 cells, suggesting that the metabolic fate of n-1 PUFA is distinct from that of common PUFA.

kn-title=Prolonged exposure to axitinib alters the molecular profile of Caki‑2 renal cell carcinoma cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Axitinib, an oral second‑generation multitargeted tyrosine kinase inhibitor, is used as a second‑line treatment for metastatic renal cell carcinoma (RCC). However, patients often develop resistance after initial responsiveness, necessitating the elucidation of the underlying resistance mechanisms. Therefore, the present study aimed to investigate the mechanisms underlying axitinib resistance using the Caki‑2 human papillary RCC model cells. Cells tolerating 0.1 µM axitinib were designated as Caki/AX cells. Cell viability was assessed using the water‑soluble tetrazolium salt assay. Notably, the 50% inhibitory concentration (IC50) values of axitinib and sunitinib were significantly higher in Caki/AX cells than those in Caki‑2 cells, indicating 2.83‑ and 1.2‑fold resistance, respectively. By contrast, the IC50 values of sorafenib and erlotinib were decreased in Caki/AX cells. Moreover, Caki/AX cells showed resistance to everolimus, temsirolimus and rapamycin, and decreased sensitivity to vinblastine, vincristine, paclitaxel, doxorubicin and SN‑38 compared with Caki‑2 cells. Notably, etoposide, 5‑fluorouracil, cisplatin and carboplatin sensitivities were comparable in both cell types. Reverse transcription‑quantitative polymerase chain reaction (PCR) analysis revealed that the mRNA levels of the ATP‑binding cassette subfamily B member 1 and subfamily G member 2 were significantly higher in Caki/AX cells than those in Caki‑2 cells. A PCR array related to vascular endothelial growth factor signalling showed that the mRNA levels of FIGF (also known as vascular endothelial growth factor D) and sphingosine kinase 1 were upregulated, whereas those of Rac family small GTPase 2 were downregulated in Caki/AX cells. Overall, these findings suggested that the upregulation of the ATP‑binding cassette subfamily B member 1, FIGF and sphingosine kinase 1 mRNA levels, and downregulation of the Rac family small GTPase 2 mRNA levels may contribute to acquired resistance in Caki/AX cells.

kn-title=Hospital-acquired pneumonia caused by multidrug-resistant Streptococcus pneumoniae serotype 15A
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Streptococcus pneumoniae remains a common cause of community-acquired pneumonia but is an infrequent pathogen in hospital-acquired pneumonia (HAP). Non-vaccine serotypes of multidrug-resistant (MDR) S. pneumoniae strains have been emerging globally, posing an increased risk of nosocomial infection.
Case A 71 year-old man developed pneumonia on postoperative day 4 following spinal fusion surgery. Despite initial treatment with ampicillin/sulbactam, his condition deteriorated, requiring ICU admission and mechanical ventilation. Microbiological testing confirmed S. pneumoniae as a causative pathogen, and ceftriaxone was empirically administered based on the local antibiogram. However, antimicrobial susceptibility testing revealed resistant profiles to penicillin (minimum inhibitory concentration [MIC], 8 µg/mL), ceftriaxone (MIC, 16 µg/mL), meropenem (MIC, 1 µg/mL), macrolides, and clindamycin, while demonstrating susceptibility to levofloxacin and vancomycin. The therapeutic regimen was subsequently adjusted to levofloxacin, resulting in clinical improvement. The isolate was later identified as serotype 15A, sequence type 63 (ST63).
Conclusion This case highlights that MDR S. pneumoniae can cause early-onset HAP and may not be covered by standard empiric therapies, emphasizing the need for careful evaluation of treatment response. Continued surveillance of infections caused by vaccine-escape clones like MDR serotype 15A is essential, given their increasing clinical relevance.

kn-title=Should Japanese athletes undergo booster vaccination for pertussis?
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Pertussis, a highly contagious respiratory infection caused by Bordetella pertussis, has demonstrated a global resurgence in the post–COVID-19 era, with the emergence of macrolide-resistant strains. In Japan, the routine immunization schedule for pertussis remains limited compared with international standards, leaving young populations under-immunized and at elevated risk of infection. Despite international recommendations for booster vaccinations during adolescence, Japan currently provides only a four-dose primary series during infancy, without subsequent boosters. This immunization gap possibly increases the vulnerability of Japanese athletes to pertussis. Persistent cough can significantly impair athletic performance for weeks to months, posing substantial challenges to professional sports teams. To protect athletes’ health and performance capacity and prevent team-wide outbreaks, it is imperative to consider pertussis booster immunizations in Japan, especially for elite athletes. However, DTaP (diphtheria, tetanus, and acellular pertussis) (TRIBIKⓇ) is the only available vaccine in Japan, which contains higher antigen concentrations than the internationally used Tdap (tetanus, diphtheria, pertussis) vaccines (ADACEL™ and BOOSTRIXⓇ): the antigen contents of pertussis toxin, filamentous hemagglutinin, and diphtheria toxin in TRIBIKⓇ, ADACEL™, and BOOSTRIXⓇ are 23.5 µg/23.5 µg/≤15 µg, 2.5 µg/5 µg/2 µg, and 8 µg/8 µg/2.5 µg, respectively. These differences result in more severe local adverse effects in vaccinees and would complicate booster strategies in Japan. Aligning Japan’s immunization policies with international practices represents a critical step toward ensuring individual health and public safety in increasingly globalized sports environments.

kn-title=Flash vaporization and migration of iodine in the oceanic plate subduction zone
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Crustal fluids in subduction zones, such as subsurface aquifers, submarine seeps, and gas hydrate waters, are often rich in iodine (I2) and methane (CH4). Large-scale aquifers in the Kanto subduction zone, where the Pacific Plate (PAC) and the Philippine Sea Plate (PHS) are subducting, also exhibit high concentrations of I2 and CH4. However, the origin and behavior of I2 in the subduction zone are unclear, and its coexistence with CH4 remains unresolved. To investigate this, we compiled the I2 phase diagram under high-pressure and high-temperature (P–T) conditions to predict its physicochemical properties in the subduction zone. We then applied the P–T paths of subducted PAC and PHS sediments to the I2 phase diagram. Our findings reveal that I2 can exist as a liquid in the young and hot PHS subduction zone. Transient decompressions during earthquake ruptures can cause liquid iodine to flash-vaporize and be expelled from subducted sediments. Along with I2, thermogenic CH4 and hydrogen (H2) generated in the subducted sediments are also released and transported upward, likely by slab-dehydrated fluids. Additionally, H2 may enhance microbial CH4 production through hydrogenotrophic methanogenesis. In subduction zones of young and hot oceanic plates such as the PHS, crustal fluids are enriched in I2 and coexist with CH4 owing to the simultaneous expulsion of I2, CH4, and H2 from the same subducted sediments and their migration via deep fluids. Large subsurface aquifers can act as traps and reservoirs for migrating I2 and CH4, forming large-scale I2 and CH4 deposits.

kn-title=Evaluation of Fentanyl-Emerged Adverse Events and Pharmacokinetics in Neonates: A Physiologically Based Pharmacokinetic Modeling Approach
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Despite its common use for analgesia in neonatal intensive care units, the optimal dosing and safety profile of fentanyl, particularly regarding suspected fentanyl-emerged adverse events (FEAEs), such as hypotension, desaturation, and oliguria, are not well-defined.
Objective This study aimed to develop an optimal therapeutic monitoring and dosing strategy for fentanyl for neonates. A physiologically based pharmacokinetic (PBPK) model for predicting fentanyl pharmacokinetics across various populations, including preterm and term neonates, was developed, and the relationship between predicted fentanyl exposure and FEAE incidence in neonates was assessed.
Methods A PBPK model was developed and validated against the observed values in the literature. The model’s predictive accuracy for fentanyl pharmacokinetics and association with FEAE incidence in an external retrospective cohort of Japanese neonates was evaluated using the predicted concentrations and pharmacokinetic parameters estimated by PBPK simulation.
Results The PBPK model exhibited reasonable predictive performance for serum fentanyl concentrations in actual neonatal patients (mean error: 9.27% [standard error: 5.06%], root mean squared error: 54.7%). The incidence of any FEAE, particularly oxygen desaturation, was associated with the fentanyl concentration-to-dose ratio, but not with some exposure parameters, such as the area under the curve and maximum concentration. The recommended reduced infusion rate allowed serum fentanyl concentrations to fall within the ranges established by the reported values and our data.
Conclusions Our PBPK model and proposed dosing strategy may contribute to safer and more effective fentanyl use in neonates.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this study, we prepared a brookite-type titanium dioxide particle layer on the surface of titanium substrates via hydrothermal treatment in aqueous urea solutions containing sodium chloride (NaCl) and examined its in vitro apatite-forming ability. Increasing the urea concentration suppressed the formation of anatase-type titanium dioxide on the titanium substrate, forming a particle layer composed of pure brookite-type titanium dioxide. The size and packing density of brookite-type titanium dioxide particles formed on the titanium substrate increased with the NaCl concentration in a 7.0 mol·dm−3 urea solution. When titanium substrates hydrothermally treated in aqueous solutions of 7.0 mol·dm−3 urea and 2.0 mol·dm−3 NaCl were soaked in a simulated body fluid for various periods up to 7 d, the substrate surface was densely covered with hemispherical apatite particles (5.3 µm in diameter) within 3 d, indicating that the brookite-type titanium dioxide particle layer had an excellent apatite-forming ability comparable to that of the anatase-type titanium dioxide particle layer.

kn-title=Cardiac characteristics of Fabry disease from baseline enrolment data in a nationwide prospective Japanese registry
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Fabry disease (FD) is an important disease in the cardiovascular field because a significant proportion of patients with FD die from cardiac lesions.
Methods: A multicenter prospective registration study of patients with FD throughout Japan was designed. The baseline clinical characteristics of 175 patients are presented here.
Results: The mean ages at enrolment and at diagnosis were 52 ± 16 and 43 ± 18 years, respectively, with men accounting for 38 % of the patients. In the cohort, 24 % of the patients had the classical hemizygote male type, whereas 14 % had the late-onset male type, and 62 % had the heterozygote female type. On electrocardiography data at enrolment in 92 patients with left ventricular hypertrophy (LVH) (maximum LV wall thickness > 12 mm), 12 % showed a short PQ interval (< 120 msec), and 33 % had a short PendQ interval (≤ 40 msec). The Sokolow-Lyon voltage was high (6.1 ± 13.1 mv). Regarding the distribution of LVH patterns, 77 % of the patients showed concentric diffuse LVH, 16 % of the patients had asymmetric septal hypertrophy, and 1 % of the patients had hypertrophy confined to the LV apex. With regard to implantation of cardiac devices, permanent pacemakers had been implanted in 5 % of the patients and defibrillators had been implanted in 12 patients (7 %), for primary prevention in nine patients and for secondary prevention in three patients.
Conclusion: As the first large-scale prospective registry of FD patients in Japan, this study has provided valuable baseline data for the cardiac features and management of FD.

kn-title=Surface exposure ages of middle–late Pleistocene marine and fluvial terraces along the northern and southern Sanriku coasts, Northeast Japan
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=To estimate long-term rates of coastal uplift along the northern Pacific coast of Northeast Japan, we determined the surface exposure ages of marine and fluvial terraces based on terrestrial in situ cosmogenic radionuclide dating of exposed bedrock surfaces. Based on reinterpretation of marine and fluvial terraces, we collected samples from the northern and southern Sanriku coast. The surface exposure ages from 10Be concentrations in quartz calculated from the measured 10Be/9Be ratios commonly suggest MIS 5 and MIS 7 for the marine and fluvial terraces and averaged coastal uplift rates of ca. 0.25 ± 0.15 and 0.4 mm/yr along the northern and southern Sanriku coast at intermediate timescales. The results may demonstrate different styles of crustal strain accommodation in the northern Northeast Japan arc above the subducting Pacific plate.

kn-title=Role of polar localization of the silicon transporter OsLsi1 in metalloid uptake by rice roots
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Low silicon (Si) rice 1 (OsLsi1) is a key transporter mediating Si uptake in rice (Oryza sativa). It is polarly localized at the distal side of the root exodermis and endodermis. Although OsLsi1 is also permeable to other metalloids, such as boron (B), germanium (Ge), arsenic (As), antimony (Sb), and selenium (Se), the role of its polar localization in the uptake of these metalloids remains unclear. In this study, we investigated the role of OsLsi1 polar localization in metalloid uptake by examining transgenic rice plants expressing polarly or nonpolarly localized OsLsi1 variants. Loss of OsLsi1 polar localization resulted in decreased accumulation of Ge, B, and As in shoots but increased Sb accumulation, while Se accumulation remained unaffected under normal conditions. Experiments with varying B concentrations revealed that B uptake is significantly lower at low B concentrations (0.3 to 3 μm) but higher at high B concentrations (300 μm) in plants expressing nonpolarly localized OsLsi1, despite the similar B permeability of both OsLsi1 variants in Xenopus oocytes and their comparable protein abundance in roots. Additionally, the loss of OsLsi1 polarity did not affect the abundance, localization, or high B-induced degradation of the borate transporter 1 (OsBOR1), an efflux transporter that cooperates with OsLsi1 for B uptake. Taken together, our findings demonstrate that the polar localization of OsLsi1 plays a critical role in regulating metalloid uptake, depending on the presence or absence of efflux transporters cooperating with OsLsi1.

kn-title=Effects of Thoron Inhalation and Cyclosporin A Treatment on Dextran Sulfate Sodium-Induced Oxidative Damage in Mice
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Radon (222Rn; Rn) and thoron (220Rn; Tn) inhalation have been reported to enhance antioxidant activity in various organs. However, the effects of Tn on the colon have not been investigated. This study aimed to clarify the effects of Tn inhalation, alone and in combination with cyclosporin A (CsA), on dextran sulfate sodium (DSS)-induced colitis, and the accompanying oxidative stress, in mice. Male BALB/c mice were subjected to continuous 8-day Tn inhalation (c-Tn, 533±128 Bq/m3) or alternate-day Tn inhalation over the same period (f-Tn, 577±63Bq/m3), followed by treatment with 3% DSS and either CsA or vehicle for 7 days. Although the disease activity index (DAI) decreased significantly by day 2 in the c-Tn group, scores remained significantly higher than those in the f-Tn group. In the c-Tn group, superoxide dismutase and catalase activity in the colon were significantly elevated compared with those in sham controls. Thus, DSS-induced damage was effectively inhibited in the earlier stages by the c-Tn mode of inhalation than by the f-Tn mode. These findings suggest that continuous Tn inhalation more effectively attenuated early colitis symptoms than alternate-day inhalation, potentially through upregulation of antioxidant defenses. Tn and CsA showed no combined effects.

kn-title=Amelioration of Cd-induced bone deterioration by orally administered calcium phosphate
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Cadmium (Cd) is a heavy metal that accumulates in the body, primarily through daily grain intake, and has a high affinity for bone, leading to skeletal diseases such as osteomalacia and fractures. Hydroxyapatite (HAp), a major bone mineral component, is highly pH-sensitive and is known to incorporate Cd, as observed in studies of Itai-itai disease. Based on these findings, we hypothesized that HAp could serve as an effective oral detoxification material for heavy metals. This study investigated the efficacy of orally administered HAp in inhibiting Cd-induced changes in bone physical and chemical properties, comparing its effects to those of activated charcoal (AC), a common detoxifying agent. Six-week-old male ICR mice were exposed to cadmium via drinking water containing CdCl2 and subsequently given diets containing either HAp or AC for four weeks. Three-point bending tests, micro-CT analysis, and histological observations of the femurs demonstrated that mice receiving HAp exhibited improved mechanical strength and enhanced bone quality protection compared to the control and other Cd-treated groups. Activated charcoal also contributed to bone quality improvement at low concentrations, but its effect diminished at high concentrations. These results suggest that the oral administration of HAp may be a promising therapeutic strategy for suppressing cadmium-induced osteomalacia.

kn-title=Fourier-transform infrared spectroscopy of hydrogen fluoride dimers in solid parahydrogen
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We investigate the Fourier-transform infrared spectra of hydrogen fluoride dimers in solid parahydrogen, the detailed analysis of which has remained unexplored. We propose a plausible analysis based on concentration dependence, light polarization, annealing, and time evolution. The absorption lines exhibited multiple peaks, with intensity ratios significantly altered by annealing and by time evolution at a constant temperature. The spectral patterns and isotopic effects suggest that the dimers do not rotate freely in solid parahydrogen, while multiple peaks arise from different stable structures, including single and double substitution sites. Unlike in the gas phase and helium droplets, no tunneling splitting was observed. The broad ν1 band suggests that some dimer structures may exhibit axial rotation. Spectral changes due to annealing likely result from site conversion, while observed IR-induced changes indicate preferential dissociation of dimers in double substitution sites. These findings still remain tentative, necessitating further experimental and theoretical studies.

kn-title=Effects of Metal-Cation Doping on Photocatalytic H2 Evolution Activity of Layered Perovskite Oxynitride K2LaTa2O6N
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Aliovalent cation doping into a heterogeneous photocatalyst affects several of its physicochemical properties, including its morphological characteristics, optical absorption behavior, and charge carrier dynamics, causing a drastic change in its photocatalytic activity. In the present work, we investigated the effects of aliovalent cation doping on the visible-light H2-evolution photocatalytic activity of the Ruddlesden–Popper layered perovskite oxynitride K2LaTa2O6N. The photocatalytic activity toward H2 evolution from an aqueous NaI solution was found to be enhanced by an increase in the specific surface area of the K2LaTa2O6N photocatalyst, which could be realized upon doping with lower-valence cations (e.g., Mg2+, Al3+, and Ga3+). Among the dopants examined at 1 mol % doping, Ga resulted in the highest activity. The activity of the Ga-doped specimen was further improved with increasing Ga concentration, where the maximal activity was obtained at 10 mol %, corresponding to an apparent quantum yield of 2.7 ± 0.4% at 420 nm from aqueous methanol. This number is the highest reported for a layered oxynitride photocatalyst. In the Ga-doped K2LaTa2O6N, a trade-off was observed between the Ga concentration and the photocatalytic activity. Although doping with Ga reduced the particle size of K2LaTa2O6N and suppressed undesirable charge recombination, it led to an enlarged bandgap, unsuitable for visible-light absorption.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The toxicity of two herbicides (diuron and bromacil) and three antibiotics (clarithromycin, azithromycin, and clindamycin) was evaluated for on four marine phytoplankton species: two diatoms, Skeletonema costatum and Chaetoceros lorenzianus, a dinoflagellate, Prorocentrum shikokuense, and a raphidophyte, Heterosigma akashiwo. The 50 % effective concentrations (EC50-μ) for growth of the herbicides (approximately 2.3–24.3 μg L−1) were lower than those of the antibiotics, indicating their higher toxicity. The EC50-μ of diuron was close to its reported environmental concentrations. The EC50-μ values for the antibiotics substantially differed by species, ranging from 19.5 to > 1000 μg L−1, with diatoms showing higher sensitivity than flagellates. Herbicides inhibited the photosynthetic yield (φII) of all tested species at concentrations similar to or lower than those affecting growth, while antibiotics affected φII at higher concentrations. Under high-light conditions, photosynthesis in S. costatum was substantially inhibited by all chemicals except clindamycin, suggesting enhanced chemical toxicity under intense light. Overall, these findings indicate that these herbicides and antibiotics can alter phytoplankton abundance and composition in coastal areas and that environmental factors, such as increased solar radiation, can potentially enhance their toxicity.

kn-title=PEGylation of liposome-encapsulated midazolam does not improve the bioavailability of midazolam when administered orally
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Liposomes are closed vesicles made of the same phospholipid bilayer as biological membranes and are capable of containing drugs, and so they have been investigated as useful drug carriers for drug delivery. We previously developed liposome-encapsulated midazolam (LE-midazolam) for oral administration, but midazolam is metabolized in the liver, and for clinical use the encapsulation of the liposomes needed to be improved to increase the bioavailability of midazolam. The surfaces of pharmaceutical liposomes are generally coated with polyethylene glycol (PEGylation) because it prevents their capture by phagocytes and helps them to avoid the reticuloendothelial system. Therefore, we considered that PEGylation could reduce the metabolism of orally administered encapsulated midazolam in the liver.
Methods Midazolam solution, LE-midazolam solution, and PEGylated liposome-encapsulated midazolam (PEG-LE-midazolam) solution were prepared, and the characteristics of the liposomes in these solutions were evaluated. Furthermore, these solutions were orally administered to rabbits, and the resultant plasma midazolam concentrations were measured. The effects of the PEGylation of LE-midazolam on the plasma concentration and bioavailability of orally administered midazolam were also evaluated.
Results The PEG-LE-midazolam solution contained a higher percentage of larger liposomes than the LE-midazolam solution. The area under the concentration-time curve (AUC) of the LE-midazolam solution was significantly higher than that of the midazolam solution, but there was no difference between the AUC values of the PEG-LE-midazolam and midazolam solutions.
Conclusions These findings suggest that liposome encapsulation may reduce the first-pass effect following oral administration, but PEGylation is not expected to improve the bioavailability of orally administered midazolam.

kn-title=Novel leukocytapheresis method using highly concentrated sodium citrate solution for the manufacturing of tisagenlecleucel
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=For the manufacturing of tisagenlecleucel (tisa-cel) requires the non-mobilized mononuclear cell collection (MNC). CD3+ cell collection is performed using the same protocol as autologous peripheral blood stem cell harvest (auto-PBSCH), but this procedure necessitates the same target CD3+ cell yields regardless of age or body weight, which may take several days especially in pediatric and small female patients with low white blood cell counts. We previously demonstrated a novel method using highly concentration sodium citrate (HSC), which reduced the need for an anticoagulant (AC) solution and shortened the procedure time in auto-PBSCH. This novel method was expected to offer advantages for smaller patients, prompting us to investigate its application in leukocytapheresis for the manufacturing of tisa-cel. We retrospectively analyzed consecutive leukocytapheresis data obtained using Spectra Optia continuous MNC mode between November 2022 and June 2024 at our institution (n = 9). In six of nine patients, pre-leukocytapheresis CD3+ cell counts were less than 500 /μL, but all could obtain the target CD3+ cell yields in one day upon processing blood volume adjustment. When we compared patients who had received CD3+ cell collection using normal-concentration sodium citrate (NSC) as our previously reported using propensity score-matched pair analysis, the total AC solution volume was significantly lower (1168 vs. 316 mL, p < 0.001) and procedure time was significantly shorter (254 vs. 228 min, p = 0.04) in the HSC group compared to the NSC group. In conclusion, this procedure was also useful for non-mobilized MNC. Our findings warrant validation in a larger patient cohort.

en-abstract=
kn-abstract=Background: As the processed blood volume increases, a larger amount of anticoagulant (AC) is required, which leads to a serious issue of fluid dilution in large-volume leukocytapheresis (defined as ≥3-fold total blood volume). We previously reported a novel method for allogeneic peripheral blood stem cell harvest (PBSCH) using highly concentrated sodium citrate (HSC; 5.32%), which shortened the procedure time and reduced the need for an AC solution without heparin. In this study, we extended this novel method to autologous PBSCH (auto-PBSCH) and compared it with patients who received auto-PBSCH using normal concentrated sodium citrate (NSC; 2.2%).
Study Design and Methods: We retrospectively analyzed consecutive auto-PBSCH data obtained using the Spectra Optia continuous mononuclear cell collection mode between May 2017 and May 2025 at our institution.
Results: Leukocytapheresis was performed using NSC in 36 patients and HSC in 22. In the HSC group, patients tended to be younger, had significantly lower body weight, and had significantly fewer hematopoietic tumors as primary diseases compared to the NSC group. After propensity score-matched cohort adjusted for patient background, the total amount of AC solution was significantly lower (694 [range, 77–1648] vs. 298 mL [range, 64–797], p = .02), and procedure time was significantly shorter (224 [range, 117–395] vs. 181 min [range, 103–309], p = .048) in the HSC group. Furthermore, the loss rates of magnesium and potassium were lower in the HSC group.
Conclusion: This novel leukocytapheresis method demonstrated the efficacy and safety in auto-PBSCH, while minimizing the patient burden.

kn-title=Association between proteinuria and mineral metabolism disorders in chronic kidney disease: the Japan chronic kidney disease database extension (J-CKD-DB-Ex)
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Chronic kidney disease-mineral and bone disorder (CKD-MBD) are recognized as a systemic disease affecting the prognosis of patients with CKD. Proper management of CKD-MBD is important to improve the prognosis of patients with CKD. Although proteinuria is recognized as a poor prognostic factor in these patients, few reports have examined its association with CKD-MBD. We examined the association between proteinuria and CKD-MBD using data from the Japan Chronic Kidney Disease Database Extension (J-CKD-DB-Ex). Among the patients registered in the J-CKD-DB-Ex, 30,977 with CKD stages G2–G5 who had serum creatinine, albumin, calcium, and phosphate concentrations measured at least once and urinalysis performed were included. The patients were divided into four groups (negative, 1+, 2+, and 3+) according to the degree of proteinuria. The association between proteinuria and CKD-MBD was examined by a logistic regression analysis. In a model adjusted for age, sex, diabetes, and the estimated glomerular filtration rate (eGFR), the odds ratio of the 3 + group compared with the negative group significantly increased to 2.67 (95% confidence interval, 2.29–3.13) for hyperphosphatemia, 2.68 (1.94–3.71) for hypocalcemia, and 1.56 (1.24–1.98) for hypomagnesemia. Proteinuria is associated with hyperphosphatemia, hypocalcemia, and hypomagnesemia in patients with CKD independently of eGFR.

kn-title=Development of Propofol-Encapsulated Liposomes and the Effect of Intranasal Administration on Bioavailability in Rabbits
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background/Objectives: Propofol is frequently used as an intravenous anesthetic and is rapidly metabolized. Therefore, if it could be administered non-invasively (e.g., orally) as premedication, it might hasten emergence from anesthesia, thereby improving patient safety. However, it undergoes extensive first-pass metabolism in the liver and intestines, limiting the route for premedication. We evaluated whether intranasal delivery of a propofol-encapsulated liposome solution improves systemic exposure and bioavailability in rabbits. Methods: A propofol-encapsulated liposome solution was administered to rabbits via the intravenous, oral, and intranasal routes. Blood propofol concentrations were measured for up to 60 min after administration and the area under the concentration–time curve (AUC0–60) and bioavailability of the propofol-encapsulated liposome solution were compared with those of the non-encapsulated propofol formulation. The differences were tested by two-way analysis of variance (ANOVA) with Šidák’s post hoc multiple-comparisons test and the Mann–Whitney test (α = 0.05). Results: The AUC0–60 for blood propofol concentrations after intravenous administration was significantly higher with the propofol-encapsulated liposome solution than with the non-encapsulated propofol formulation (3038.8 ± 661.5 vs. 1929.8 ± 58.2 ng·min/mL; p = 0.0286). By contrast, no increase in blood propofol concentrations was observed after oral administration, whereas intranasal administration increased blood propofol concentrations and yielded significantly higher bioavailability compared with the non-encapsulated propofol formulation (16.4 ± 7.3% vs. 2.0 ± 1.2%; p = 0.0286). Conclusions: The findings of the present study suggest that intranasal liposomal propofol increased systemic availability compared with a non-encapsulated formulation, supporting further evaluation as a candidate premedication approach for propofol.

kn-title=Current Status of Continuous Renal Replacement Therapy in Japanese Intensive Care Units: A Multicenter Retrospective Observational Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: Continuous renal replacement therapy (CRRT) is often performed for critically ill patients in intensive care units (ICUs), but its optimal indication and settings have yet to be determined. Thus, we aimed to describe the current status of CRRT in Japan through a multicenter retrospective observational study. Methods: Adult ICU patients receiving CRRT at 18 tertiary hospitals in Japan (up to 100 patients from each hospital over the past year) were retrospectively enrolled. Patients receiving CRRT for <24 h or intermittent renal replacement therapy together with CRRT were excluded. The primary outcomes were the temporal changes in the electrolyte levels, acid-base balance, and uremia-related small solute concentrations. The secondary outcomes included potassium (K) and phosphate (P) supplementations during CRRT. Results: Altogether, 1,045 patients were enrolled. The median CRRT duration and dose were 4.4 days and 17.3 mL/kg/h, respectively. The electrolyte levels, acid-base balance, and uremia-related small solute concentrations returned to normal by day 4 of treatment. A total of 732 (70.0%) patients received K supplementation, and only a few patients had hypokalemia until day 5. Moreover, 414 (39.6%) patients received P supplementation, and approximately 30%–50% of the patients had hypophosphatemia until day 5. Conclusion: The CRRT dose in Japan was lower than that was recommended by the Kidney Disease: Improving Global Outcomes guideline. The electrolyte level abnormalities and acid-base imbalances of the studied patients were improved within 72–96 h of CRRT. Contrarily, K and P supplementations were common, indicating that the current CRRT solutions need to be modified.

kn-title=Biochar-amended Sediment Microbial Fuel Cells for Water Quality Improvement in Intensive and Extensive Pond Drainages in Central Vietnam
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The use of nutrient-rich feed in shrimp farming in Central Vietnam has led to high nitrogen (N) and phosphorus (P) contents in the pond sediment. The objectives of the study were to assess the effectiveness of biochar-sediment microbial fuel cells (BC-SMFCs) in suppressing P and N release from two types of sediment in intensive (Int) and extensive (Ext) pond drainages in Central Vietnam. Single chamber SMFCs were set up and operated under open or closed-circuit (no SMFC or SMFC) conditions. Coconut shell biochar (BC) was amended to sediments at 1%. For Int-sediment, total phosphorus (TP) release was reduced by no BC-SMFCs through co-precipitation with Fe. On the other hand, BC-SMFCs did not suppress TP release because P was released from BC and organic matter decomposition was enhanced in the sediment. Application of BC enhanced organic N mineralization in the sediment. Nitrification and denitrification occurred in the overlying water, reducing mineral N concentrations. For Ext-sediment, BC addition and SMFC conditions did not affect TP and total nitrogen (TN) release because of low initial organic matter content, and less reductive condition. Our study suggested that the effect of SMFCs was masked by BC which released more P from Int-sediment to the water.

kn-title=Evaluating the effects of electrolytes on the interaction forces between alumina surfaces in polyacrylic acid solutions using atomic force microscopy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Evaluation and control of ceramic slurry at the microscopic level are critical to ensure consistent quality in manufactured ceramics. Notably, metal ions such as Mg2+ and Al3+ are common in ceramic slurries and significantly influence the stability of particle. This study applied atomic force microscopy to investigate the interaction forces between alumina particle surfaces in the presence of different concentrations of three metal ions and polyacrylic acid (PAA), a widely used dispersant.
The attractive forces observed at low PAA concentrations were attributed to polymer bridging between alumina surfaces, whereas the repulsive forces observed at high PAA concentrations were attributed to the domination of steric repulsion between adsorbed PAA molecules. The presence of multivalent metal ions, such as Mg2+ and Al3+, modulated these interactions; an increasing ion valence induced a transition from repulsive to attractive force, primarily owing to electrostatic screening, which caused conformational collapse of the PAA chains and diminished the range of steric repulsion. Similarly, increasing the concentration of these metal ions decreased the range of repulsive forces, eventually resulting in a net attraction driven by the same electrostatic and polymer conformation mechanisms. Notably, the addition of 0.1 M AlCl3 produced an anomalous long-range attraction between surfaces that could not be explained by conventional mechanisms, such as polymer bridging or electrostatic interactions between charge domains.

kn-title=Introduction to the “Japanese and Western approaches to psychotrauma” symposium
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Understandings of psychotrauma have changed throughout medical history, shaped by cultural and social factors. Reviewing transcultural perspectives of psychotrauma helps understand its complexities and contextual impacts. This paper summarizes the Japan–Netherlands symposium on psychotrauma held on March 1, 2024. Despite experiencing psychological trauma from World War II and numerous natural disasters, Japan did not actively research post-traumatic stress disorder (PTSD) for nearly 50 years after the war. The Great Hanshin-Awaji Earthquake and the Tokyo subway Sarin gas attack (1995) popularized the term PTSD in Japan and triggered related research. The absence of psychotrauma research in Japan may reflect a form of state-level PTSD, characterized by avoidance. Japan’s collectivist culture, stigma against seeking psychological help, view of patience as a virtue, survivor guilt, and moral injury were potential related factors. Additionally, sociocultural factors (e.g., insufficient collective grieving and focusing on post-war reconstruction) were discussed as potential hinderances to discussing war experiences. From a European perspective, we examined how “Konzentrationslager” (KZ) syndrome, a trauma-related disorder, evolved independently into diverse conceptual frameworks, ultimately contributing to the acceptance of PTSD following its introduction in 1980. Beyond state compensation for concentration camp survivors, advocacy by feminist movements and veterans' groups increased awareness of psychotrauma across Europe, fostering scholarly research and public discourse. Both PTSD and KZ syndromes are diagnostic categories shaped by specific historical and cultural contexts and should not be regarded as simple, universally applicable medical conditions. They reflect how trauma is interpreted and responded to differently depending on cultural, political, and historical factors.

en-abstract=
kn-abstract=We report the case of a 72-year-old Japanese man with an incidental portal vein mass that was surgically resected and diagnosed as immunoglobulin G4 (IgG4)-related disease. The mass was discovered during an atrial fibrillation examination. The patient had a history of gastric cancer and was also diagnosed with rectal cancer, raising concerns about metastasis. Due to technical challenges, a biopsy was not feasible. Imaging findings suggested portal vein tumor thrombosis, complicating the diagnosis. This case highlights a rare presentation of IgG4-related disease mimicking portal vein tumor thrombus.

kn-title=The response to thermospermine is fine-tuned by the balance between SAC51 and LHW family proteins in Arabidopsis thaliana
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Thermospermine negatively regulates xylem formation. In Arabidopsis, SAC51 and SACL3, members of the SAC51 gene family encoding basic loop-helix-loop (bHLH) proteins play a key role in this regulation. These mRNAs contain an upstream open-reading-frame (uORF) that is highly conserved across species, and its inhibitory effect on the main ORF translation is alleviated by thermospermine. A double knockout of SAC51 and SACL3 results in thermospermine insensitivity at high concentrations that normally inhibit xylem formation and shoot growth in the wild type. Conversely, uORF mutants of SAC51, SACL3, and SACL1 suppress the excessive xylem formation and dwarf phenotype of acl5, a mutant defective in thermospermine biosynthesis. In this study, we generated genome-edited uORF mutants of SACL2 and confirmed that they partially recover the acl5 phenotype. All uORF mutants exhibited increased sensitivity to thermospermine. SACL3 represses the function of LHW, a key bHLH transcription factor required for xylem proliferation, through direct interaction. We found that the lhw mutant is also hypersensitive to thermospermine, while this sensitivity was suppressed by the sac51 sacl3 double knockout. Yeast two-hybrid assays demonstrated that all four SAC51 family members interact with LHW and its family members. These findings suggest that overaccumulation of SAC51 family proteins leads to thermospermine hypersensitivity by repressing the function of LHW family proteins, whose activity must be fine-tuned to ensure proper xylem development.

kn-title=Spatiotemporal evolution of ecosystem carbon storage under land use/land cover dynamics in the coastal region of Central Vietnam
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Ecosystem carbon storage is a cost-effective strategy for global climate change mitigation, and its fluctuation is markedly shaped by land use/land cover (LULC) dynamics. Taking Danang city as an example of Central Coastal Vietnam, this study aims to assess LULC changes and analyze the spatiotemporal evolution of carbon storage from 2023 to 2050 under four LULC change scenarios, including natural trend scenario (NTS), ecological protection scenario (EPS), economic development scenario (EDS), and cropland protection scenario (CPS), by integrating the support vector machine-cellular automata-Markov (SVM-CA-Markov) model and the InVEST model. The Optimal Parameters-based Geographical Detector (OPGD) model was subsequently employed to elucidate the impacts of driving factors on the spatial distribution of carbon storage. The results showed that, from 2007 to 2023, Danang city experienced a dramatic back-and-forth transformation between LULC types, with the predominant transitions being from natural forest to acacia tree-dominated plantation forest (6492.31 ha), and from cropland to settlements, acacia tree-dominated plantation forest, and other land (5483.05 ha, 3763.66 ha, 2762.35 ha, respectively). Between 2023 and 2050, LULC transformations in Danang city are projected to yield varying degrees of carbon storage levels across different scenarios. Specifically, carbon storage is anticipated to dwindle by 0.221 Mt, 0.223 Mt, and 0.298 Mt under NTS, EDS, and CPS, respectively, while enhancing by 0.141 Mt under EPS. Regarding the spatial distribution of carbon storage, high values will be chiefly found in the western high-elevation mountainous region, while low values will be concentrated mostly in the eastern lower-lying areas of the city. Additionally, elevation and temperature acted as the two most significant driving factors influencing the spatial distribution of carbon storage, with Q values of 0.88 and 0.86 (p-value < 0.05), respectively. For interaction detection, the combination of elevation and soil exhibited a synergistic reinforcement effect on the spatial partitioning of carbon storage, with a high Q value of 0.9566 (p-value < 0.05). Our study highlights the necessity of ecological conservation measures in Danang city in the on-track pursuit of national net-zero carbon emissions by 2050.

kn-title=Study on an Effective Coolant Supply Method in the Side Plunge Grinding Process
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Grinding is widely used for finishing components with journal and thrust surfaces, such as crankshafts. Side-plunge grinding enables the simultaneous finishing of thrust and cylindrical surfaces in a single plunge. However, compared to cylindrical grinding, it involves a larger contact area between the grinding wheel and the workpiece, leading to increased heat generation. In particular, poor coolant penetration near internal corners can degrade surface quality, potentially causing stress concentrations and cracks. To enhance coolant effectiveness in side-plunge grinding, this study installs a high-pressure nozzle that supplies coolant from the side of the grinding wheel. The effectiveness of this setup is experimentally verified. Additionally, the distribution of coolant flow within the contact area between the grinding wheel and the workpiece is measured to determine the optimal nozzle position for efficient coolant delivery. The nozzle’s performance is evaluated by measuring the workpiece surface temperature using a wire/workpiece thermocouple, the amount of coolant discharged from the grinding wheel, and the residual stress distribution. The results show that coolant penetrates the grinding wheel and effectively reaches the grinding zone, enhancing the cooling effect. This study clarifies the relationship between effective coolant supply and the position of the side nozzle. Considering physical constraints, such as potential interference during grinding, the optimal nozzle location is as close as possible to both the edge of the grinding wheel and the workpiece. This positioning ensures maximum coolant delivery, reduces grinding temperature, and helps suppress drastic variations in residual stress.

kn-title=Phosphorylated pullulan as a local drug delivery matrix for cationic antibacterial chemicals to prevent oral biofilm
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Preventing oral infections, such as oral caries and periodontal disease, helps reduce the risks of various systemic diseases. In this study, the polysaccharide pullulan produced by the black yeast Aureobasidium pullulans was modified in combination with the cationic surfactant cetylpyridinium chloride (CPC) to create a local drug delivery system, and its antibacterial potential on oral bacteria was examined in vitro.
Methods Pullulan was phosphorylated at the CH2OH residue of α6 in the maltotriose structure and mixed with CPC. Bacterial attachment of cariogenic Streptococcus mutans on hydroxyapatite plates (HAPs) treated with the phosphorylated pullulan (PP) and CPC compound (0.01% PP and 0.001– 0.03% CPC, and vice versa) was assessed by observing bacteria using a field emission scanning electron microscope (FE-SEM) and quantified through 16 S rRNA amplification via real-time polymerase chain reaction (PCR). Additionally, the quartz crystal microbalance (QCM) method was employed to evaluate the sustained release of CPC.
Results PP-CPC compound maintained significant bactericidal activity even at 0.01%, which is one-fifth of the conventional applicable concentration of CPC. Additionally, a residual mixture was detected by the hydroxyapatite sensor of the crystal oscillator microbalance detector, suggesting an unknown molecular interaction that enables the sustained release of CPC after attachment to hydroxyapatite.
Conclusions The combination of PP and CPC may contribute to the low concentration and effective prevention of oral infections, such as dental caries.

kn-title=Cross-feeding between beneficial and pathogenic bacteria to utilize eukaryotic host cell-derived sialic acids and bacteriophages shape the pathogen-host interface milieu
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Under an inflamed-intestinal milieu, increased free sialic acids are associated with the overgrowth of some pathogenic bacterial strains. Recently, the protective immunomodulatory activity of gut bacteriophages (phages) has also been highlighted. However, the role of phages in triple reciprocal interactions between pathogenic bacteria, beneficial bacteria, and their host cell sialic acids has not been studied so far. We established a sialidase-explicit model in which beneficial and pathogenic bacteria interact through cross-feeding and competition for free sialic acid using a human triple co-culture cell model incorporating colonocytes (T84 cells), monocytes (THP-1 cells), and hepatocytes (Huh7 cells). Triple co-cultured cells were challenged with Gram-positive Bifidobacterium bifidum (B. bifidum) and Gram-negative Pseudomonas aeruginosa PAO1 (P. a PAO1) in the absence or presence of its KPP22 phage in two different cell culture mediums: 1) standard Dulbecco's Modified Eagle Medium (DMEM) and 2) DMEM with 2,3-dehydro-2-deoxy-N-acetylneuraminic acid (DANA). Changes in physiological, functional, and structural health markers of stimulated cocultured cells were evaluated. The concentrations of sialic acid and pro-inflammatory cytokines in the cell culture supernatants were quantified. P. a PAO1 triggered the release of interleukin 6 and 8 (IL-6 and IL-8), accompanied by increased levels of free sialic acid, reduced viability of co-cultured cells, and disrupted the integrity of the cellular monolayer. These disruptive effects were markedly attenuated by KPP22 phage and B. bifidum. In addition to well-documented differences in the structure and composition of the bacterial cell walls of Gram-negative pathogenic bacteria and bifidobacteria, two distinct factors seem to be pivotal in modulating the pathogen-host interface milieu: (i) the presence of phages and (ii) the utilization of free sialic acids secreted from host cells by bifidobacteria.

kn-title=Novel Anti-MRSA Peptide from Mangrove-Derived Virgibacillus chiguensis FN33 Supported by Genomics and Molecular Dynamics
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Antimicrobial resistance (AMR) is a global health threat, with methicillin-resistant Staphylococcus aureus (MRSA) being one of the major resistant pathogens. This study reports the isolation of a novel mangrove-derived bacterium, Virgibacillus chiguensis FN33, as identified through genome analysis and the discovery of a new anionic antimicrobial peptide (AMP) exhibiting anti-MRSA activity. The AMP was composed of 23 amino acids, which were elucidated as NH3-Glu-Gly-Gly-Cys-Gly-Val-Asp-Thr-Trp-Gly-Cys-Leu-Thr-Pro-Cys-His-Cys-Asp-Leu-Phe-Cys-Thr-Thr-COOH. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for MRSA were 8 µg/mL and 16 µg/mL, respectively. FN33 AMP induced cell membrane permeabilization, suggesting a membrane-disrupting mechanism. The AMP remained stable at 30–40 °C but lost activity at higher temperatures and following exposure to proteases, surfactants, and extreme pH. All-atom molecular dynamics simulations showed that the AMP adopts a β-sheet structure upon membrane interaction. These findings suggest that Virgibacillus chiguensis FN33 is a promising source of novel antibacterial agents against MRSA, supporting alternative strategies for drug-resistant infections.

kn-title=Integration of Cholesterol Oxidase‐Based Biosensors on a Smart Contact Lens for Wireless Cholesterol Monitoring from Tears
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease. Regular cholesterol monitoring is essential for elderly or obese individuals. Current methods, such as blood tests, are invasive, inconvenient, and require a professional operator. In contrast, tears, as an accessible body fluid, offer a promising alternative for noninvasive monitoring due to their correlation with blood cholesterol levels. Herein, a noninvasive approach for monitoring cholesterol levels in tears using a biosensor integrated into a smart contact lens is reported. The biosensor employs cholesterol oxidases as the biocatalyst, coupled with an osmium-based mediator, to detect cholesterol concentrations ranging from 0.1 mM to 1.2 mM in artificial tears. A key challenge is the extremely low cholesterol concentration in tears, which is addressed using a parity-time (P-T) symmetry-based magnetic resonance coupling system. This system enables wireless signal reading and achieves high sensitivity due to its high-quality (Q) factor, which can achieve a detection limit of 0.061 mM. This portable, high-sensitivity smart contact lens demonstrates significant potential as a wearable device for continuous, noninvasive cholesterol monitoring. The findings contribute to advancing tear-based diagnostic systems and highlight the scientific importance of utilizing tear biomarkers for health monitoring.

kn-title=Unveiling a New Antimicrobial Peptide with Efficacy against P. aeruginosa and K. pneumoniae from Mangrove-Derived Paenibacillus thiaminolyticus NNS5-6 and Genomic Analysis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study focused on the discovery of the antimicrobial peptide (AMP) derived from mangrove bacteria. The most promising isolate, NNS5-6, showed the closest taxonomic relation to Paenibacillus thiaminolyticus, with the highest similarity of 74.9%. The AMP produced by Paenibacillus thiaminolyticus NNS5-6 exhibited antibacterial activity against various Gram-negative pathogens, especially Pseudomonas aeruginosa and Klebsiella pneumoniae. The peptide sequence consisted of 13 amino acids and was elucidated as Val-Lys-Gly-Asp-Gly-Gly-Pro-Gly-Thr-Val-Tyr-Thr-Met. The AMP mainly exhibited random coil and antiparallel beta-sheet structures. The stability study indicated that this AMP was tolerant of various conditions, including proteolytic enzymes, pH (1.2–14), surfactants, and temperatures up to 40 °C for 12 h. The AMP demonstrated 4 µg/mL of MIC and 4–8 µg/mL of MBC against both pathogens. Time-kill kinetics showed that the AMP acted in a time- and concentration-dependent manner. A cell permeability assay and scanning electron microscopy revealed that the AMP exerted the mode of action by disrupting bacterial membranes. Additionally, nineteen biosynthetic gene clusters of secondary metabolites were identified in the genome. NNS5-6 was susceptible to various commonly used antibiotics supporting the primary safety requirement. The findings of this research could pave the way for new therapeutic approaches in combating antibiotic-resistant pathogens.

kn-title=Lithium- and oxygen-isotope compositions of a Si-rich nebular reservoir determined from chondrule constituents in the Sahara 97103 EH3 chondrite
en-subtitle=

kn-abstract=Here we report the in situ ion-microprobe analyses of the Li- and O-isotope compositions of enstatite, FeO-rich pyroxene, olivine, glass, and cristobalite grains from six chondrule-related objects from the Sahara 97103 EH3 chondrite. The O-isotope composition of the enstatite grains scattered around the intersection between the terrestrial fractionation and primitive chondrule minerals lines. Whereas, that of olivine varied along the primitive chondrule minerals line. Based on the mineralogy, we found cristobalite formed as a result of Si saturation, instead of the reduction of FeO-rich silicates, consistent with Si-enrichment of whole rock enstatite chondrites. Based on the mineralogy and O-isotope compositions, we infer that olivines in some chondrules are relict grains. In chondrules that contained olivine, no abundant niningerite [(Mg,Fe,Mn)S] was observed. Thus, enstatite formation can be explained by the interaction of an olivine precursor with additional SiO2 (Mg2SiO4 + SiO2 → Mg2Si2O6), instead of sulfidation (Mg2SiO4 + S → 1/2 Mg2Si2O6 + MgS + 1/2 O2). Using the equation Mg2SiO4 + SiO2 → Mg2Si2O6 and the O-isotope compositions of enstatite and olivine, the O-isotope composition of the additional SiO2 was estimated. Based on the O-isotope composition, we infer that there could be a Si-rich gas with an elevated Δ17O value similar to, or greater than the second trend line (Δ17O = 0.9 ‰) suggested by Weisberg et al. (2021), during chondrule formation. The variation in the Li-isotope compositions of enstatite and olivine grains from EH3 chondrules is smaller than that for the same phases from CV3 chondrules. The variation in the Li-isotope compositions of the enstatite and olivine grains from EH3 chondrules is also smaller than that of their O-isotope compositions. During the recycling of enstatite-chondrite chondrules, both Li- and O-isotope compositions were homogenized. Although enstatite is the major carrier of Li in EH3 chondrules, the Li-isotope composition (δ7Li) of enstatite is lower than that of whole rock EH3 chondrites, suggesting the existence of a phase with higher δ7Li. Meanwhile, the Li-isotope composition and concentration (δ7Li, [Li]) of enstatite is higher than that of olivine. The Li-isotope composition of the Si-rich gas was estimated to be δ7Li = 1 ‰, using a similar mass-balance calculation as applied for the O-isotope composition. The Li-isotope composition of the Si-rich gas from the enstatite-chondrite-chondrule forming-region, is consistent with that of whole rock EH3 chondrites, and differs significantly from that of the Si-rich gas from the carbonaceous-chondrite-chondrule forming-region (δ7Li = −11 ‰) determined by a previous study. We speculate that the Si-rich gas in the carbonaceous-chondrite-chondrule forming-region maintained the Li-isotope heterogeneity inherited from light lithium synthesized by galactic cosmic-ray spallation in the interstellar medium.

kn-title=Stem Cell Factors BAM1 and WOX1 Suppressing Longitudinal Cell Division of Margin Cells Evoked by Low-Concentration Auxin in Young Cotyledon of Arabidopsis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Highly differentiated tissues and organs play essential biological functions in multicellular organisms. Coordination of organ developmental process with tissue differentiation is necessary to achieve proper development of mature organs, but mechanisms for such coordination are not well understood. We used cotyledon margin cells from Arabidopsis plant as a new model system to investigate cell elongation and cell division during organ growth and found that margin cells endured a developmental phase transition from the “elongation” phase to the “elongation and division” phase at the early stage in germinating seedlings. We also discovered that the stem cell factors BARELY ANY MERISTEM 1 (BAM1) and WUSCHEL-related homeobox1 (WOX1) are involved in the regulation of margin cell developmental phase transition. Furthermore, exogenous auxin treatment (1 nanomolar,nM) promotes cell division, especially longitudinal cell division. This promotion of cell division did not occur in bam1 and wox1 mutants. Based on these findings, we hypothesized a new “moderate auxin concentration” model which emphasizes that a moderate auxin concentration is the key to triggering the developmental transition of meristematic cells.

kn-title=Impact of pre-reconstruction filtering with butterworth filter on 111In-pentetreotide SPECT image quality and quantitative accuracy: A phantom study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: This study evaluates the image quality and quantitative accuracy of SPECT images with pre- and post-reconstruction smoothing filters in somatostatin receptor scintigraphy using phantom data.
Methods: We evaluated the spatial resolution, the contrast-to-noise ratio (CNR), and the quantitative accuracy using a NEMA IEC body phantom filled with a 111In solution. SPECT images were obtained with a Siemens Symbia T16 SPECT/CT system. Quantitative accuracy refers to the ability to accurately estimate the radioactive concentration of 111In in the phantom from the image. SPECT reconstructions were performed using three methods: post-reconstruction Gaussian filtering (post-G), pre-reconstruction Gaussian filtering (pre-G), and pre-reconstruction Butterworth filtering (pre-B). To verify each filtering method, the cut-off frequency of the Butterworth filter and the full width at half maximum (FWHM) of the Gaussian filter were each changed to eight different settings.
Results: FWHMs were 21.2, 19.8, and 18.0 mm for post-G, pre-G, and pre-B. CNRs (37-mm sphere) were 47.2, 63.8, and 69.5. Pre-B showed a 12.0 % error rate at 0.40 cycles/cm, while post-G and pre-G showed 20.2 % and 22.0 % at 7.2-mm FWHM. Pre-B outperformed other methods for resolution, CNR, and quantitative accuracy.
Conclusion: For 111In-pentetreotide SPECT images, image reconstruction with a Butterworth filter applied to the projection image before reconstruction was found to be superior to reconstruction with a Gaussian filter in terms of image quality and quantitative accuracy.
This method can be easily implemented in routine clinical SPECT imaging workflows and has the potential to improve diagnostic confidence.
Implications for practice: The proposed method with a pre-reconstruction Butterworth filter has great potential to improve the image quality and quantitative accuracy of 111In-SPECT images.

kn-title=Optimization of Preemptive Therapy for Cytomegalovirus Infections With Valganciclovir Based on Therapeutic Drug Monitoring: Protocol for a Phase II, Single-Center, Single-Arm Trial
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Valganciclovir (VGCV) is the first-line drug for preemptive therapy of cytomegalovirus (CMV) infections. However, even when administered at the dose specified in the package insert, there is significant interindividual variability in the plasma concentrations of ganciclovir (GCV). In addition, correlations have been reported between the area under the concentration–time curve and therapeutic efficacy or adverse events. Therefore, therapeutic drug monitoring (TDM) can be used to improve the efficacy and safety of preemptive VGCV therapy.
Objective: This study aims to evaluate whether the dosage adjustment of VGCV based on TDM in patients undergoing preemptive therapy for CMV infections is associated with the successful completion rate of treatment without severe hematological adverse effects.
Methods: This phase II, single-center, single-arm trial aims to enroll 40 patients admitted at the Department of Rheumatology and Clinical Immunology, Kobe University Hospital, who will receive oral VGCV as preemptive therapy for CMV infections. Participants will begin treatment with VGCV at the dose recommended in the package insert, with subsequent dose adjustments based on weekly TDM results. The primary end point will be the proportion of patients who achieve CMV antigenemia negativity within 3 weeks without severe hematological adverse events. The secondary end points will include weekly changes in CMV antigen levels, total VGCV dose, and duration of preemptive therapy. For safety evaluation, the occurrence, type, and severity of VGCV-related adverse events will be analyzed. Additionally, this study will explore the correlations between the efficacy and safety of preemptive therapy and the pharmacokinetic parameters of GCV, CMV-polymerase chain reaction values, and nudix hydrolase 15 (NUDT15) genetic polymorphisms. The correlation between GCV plasma concentrations obtained from regular venous blood and blood concentrations will be examined using dried blood spots.
Results: This study began with patient recruitment in September 2024, with 5 participants enrolled as of June 16, 2025. The target enrollment is 40 participants, and the anticipated study completion is set for July 2027.
Conclusions: This is the first study to investigate the impact of TDM intervention in patients receiving VGCV as preemptive therapy. The findings are postulated to provide valuable evidence regarding the utility of TDM in patients receiving VGCV as preemptive therapy.

kn-title=A plant-insertable multi-enzyme biosensor for the real-time monitoring of stomatal sucrose uptake
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Monitoring sucrose transport in plants is essential for understanding plant physiology and improving agricultural practices, yet effective sensors for continuous and real-time in-vivo monitoring are lacking. In this study, we developed a plant-insertable sucrose sensor capable of real-time sucrose concentration monitoring and demonstrated its application as a useful tool for plant research by monitoring the sugar-translocating path from leaves to the lower portion of plants through the stem in living plants. The biosensor consists of a bilirubin oxidase-based biocathode and a needle-type bioanode integrating glucose oxidase, invertase, and mutarotase, with the two electrodes separated by an agarose gel for ionic connection. The sensor exhibits a sensitivity of 6.22 μA mM−1 cm−2, a limit of detection of 100 μM, a detection range up to 60 mM, and a response time of 90 s at 100 μM sucrose. Additionally, the sensor retained 86 % of its initial signal after 72 h of continuous measurement. Day-night monitoring from the biosensor inserted in strawberry guava (Psidium cattleianum) showed higher sucrose transport activity at night, following well the redistribution of photosynthetically produced sugars. In addition, by monitoring the forced translocation of sucrose dissolved in the stable isotopically labeled water, we demonstrated that a young seedling of Japanese cedar known as Sugi (Cryptomeria japonica) can absorb and transport both water and sucrose through light-dependently opened stomata, which is the recently revealed path for liquid uptake by higher plants. These findings highlight the potential of our sensor for studying dynamic plant processes and its applicability in real-time monitoring of sugar transport under diverse environmental conditions.

kn-title=Histidine-rich glycoprotein inhibits TNF-α–induced tube formation in human vascular endothelial cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: Tumor necrosis factor-α (TNF-α)-induced angiogenesis plays a critical role in tumor progression and metastasis, making it an important therapeutic target in cancer treatment. Suppressing angiogenesis can effectively limit tumor growth and metastasis. However, despite advancements in understanding angiogenic pathways, effective strategies to inhibit TNF-α-mediated angiogenesis remain limited.
Methods: This study investigates the antiangiogenic effects of histidine-rich glycoprotein (HRG), a multifunctional plasma protein with potent antiangiogenic properties, on TNF-α-stimulated human endothelial cells (EA.hy926). Tube formation assays were performed to assess angiogenesis, and gene/protein expression analyses were conducted to evaluate HRG’s effects on integrins αV and β8. The role of nuclear factor erythroid 2-related factor 2 (NRF2) in HRG-mediated antiangiogenic activity was also examined through nuclear translocation assays and NRF2 activation studies.
Results: At physiological concentrations, HRG effectively suppressed TNF-α-induced tube formation in vitro and downregulated TNF-α-induced expression of integrins αV and β8 at both the mRNA and protein levels. HRG treatment promoted NRF2 nuclear translocation in a time-dependent manner. Furthermore, activation of NRF2 significantly reduced TNF-α-induced tube formation and integrin expression, suggesting that NRF2 plays a key role in HRG-mediated antiangiogenic effects.
Discussion and Conclusion: Our findings indicate that HRG suppresses TNF-α-induced angiogenesis by promoting NRF2 nuclear translocation and transcriptional activation, which in turn inhibits integrin αV and β8 expression. Given the essential role of angiogenesis in tumor progression, HRG’s ability to regulate this process presents a promising therapeutic strategy for cancer treatment.

kn-title=An Underlying Mechanism for the Altered Hypoglycemic Effects of Nateglinide in Rats with Acute Peripheral Inflammation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The hypoglycemic effects of nateglinide (NTG) were examined in rats with acute peripheral inflammation (API) induced by carrageenan treatment, and the mechanisms accounting for altered hypoglycemic effects were investigated. NTG was administered through the femoral vein in control and API rats, and its plasma concentration profile was characterized. The time courses of the changes in plasma glucose and insulin levels were also examined. Although the plasma concentration profile of NTG in API rats was marginally distinguishable from that in control rats, the hypoglycemic effect of NTG was more persistent in API rats than in control rats. In addition, NTG elevated the plasma level of insulin more intensely in API rats than in control rats. Then, the islets of Langerhans were procured by perfusing the pancreas with collagenase solution in control and API rats, and the pancreatic mRNA expression of preproinsulin (Ins1), as well as that of sulfonylurea receptor ABCC8 (Abcc8), were examined. As a result, the expression of preproinsulin and ABCC8 mRNA increased in API rats. These findings suggest that the hypoglycemic effect of NTG was potentiated in API rats due to increased insulin secretion in the pancreas, which was caused by enhanced preproinsulin synthesis and expression of the sulfonylurea receptor.

kn-title=Plasma concentrations of histidine-rich glycoprotein in primary graft dysfunction after lung transplantation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=OBJECTIVES: Histidine-rich glycoprotein has been reported as an anti-inflammatory glycoprotein that inhibits acute lung injury in mice with sepsis and as a prognostic biomarker in patients with sepsis. We investigated the relationship between plasma concentrations of histidine-rich glycoprotein and the risk of occurrence of primary graft dysfunction.
METHODS: According to the primary graft dysfunction grade at post-transplant 72 h, patients who underwent lung transplantation were divided into three groups: non-primary graft dysfunction group (grade 0–1), moderate primary graft dysfunction group (grade 2), and severe primary graft dysfunction group (grade 3). The plasma concentrations of histidine-rich glycoprotein measured daily during the first post-transplant 7 days were compared among the three groups. Appropriate cutoff values of the concentrations were set for survival analyses after lung transplantation.
RESULTS: A total of 68 patients were included. The plasma histidine-rich glycoprotein concentration at post-transplant 72 h was significantly lower in the severe primary graft dysfunction group (n = 7) than in the other two groups [non-primary graft dysfunction group (n = 43), P = 0.042; moderate primary graft dysfunction group (n = 18), P = 0.040]. Patients with plasma histidine-rich glycoprotein concentration ≥34.4 µg/ml at post-transplant 72 h had significantly better chronic lung allograft dysfunction-free survival (P = 0.012) and overall survival (P = 0.037) than those with the concentration <34.4 µg/ml.
CONCLUSIONS: Plasma histidine-rich glycoprotein concentrations at post-transplant 72 h might be associated with the risk of development of primary graft dysfunction.

kn-title=Synergistic Antimicrobial Activity of BrSPR20-P1 Peptide and Silver Nanoparticles Against Pathogenic Bacteria
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Bacterial infection is a cause of life-threatening diseases. The emergence of antimicrobial-resistant bacteria exacerbates this situation, highlighting the need for the discovery of new antimicrobial agents. Our previous study identified a novel antimicrobial peptide, BrSPR20-P1 (P1), which showed potential activity against MRSA. Additionally, silver nanoparticles (AgNPs) exhibit broad-spectrum antibacterial activity, capable of killing multidrug-resistant bacteria. The combination of antimicrobial agents presents a novel strategy for combating these pathogens. This study aimed to evaluate the antibacterial activity of the combination of P1 and AgNPs. It revealed that the combinations showed synergy. The P1 and AgNP mixture at a concentration of 1 and 8 µg/mL (1:8) doubled the activity against S. aureus and MRSA, while that combination of 64 and 64 µg/mL (64:64) exhibited broad-spectrum activity, expanding to E. coli with a 32-fold increase. These combinations exhibited a bactericidal effect, showing the rapid killing of tested bacteria at 10× MIC, with killing rates during the first 3 h ranging from 4.04 ± 0.01 to 4.31 ± 0.03 h−1. The P1 and AgNP mixtures caused a low risk of antibacterial resistance up to 30 passages. It was demonstrated that the synergistic activity of P1 and AgNPs occurred through the disruption of cell walls and membranes, leakage of intracellular materials, and cell lysis. Additionally, the mixtures appeared to interact with bacterial genomic DNA, as indicated by a gel retardation assay. These activities of the combinations were concentration-dependent. The 1:8 µg/mL mixture caused low hemolysis and cytotoxicity and did not impede the wound healing process. In contrast, although the 64:64 µg/mL mixture showed excellent antibacterial efficacy, it was toxic to erythrocytes and mammalian cells. It implies that dose optimization is required to balance its efficacy and toxicity. Therefore, the P1 and AgNP combinations exhibit synergistic antimicrobial activity and have the potential to resolve bacterial infections.

kn-title=Biogeochemical impact of nickel and urea in the great oxidation event
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The Great Oxidation Event marks the first substantial increase in atmospheric oxygen on Earth. Despite the oxygenic photosynthesis that emerged hundreds of million years before this event, the specific biogeochemical mechanisms responsible for maintaining low oxygen levels for an extended period remain elusive. Here, we show the critical role of urea as a nitrogen source for cyanobacteria, the cascading impact of nickel on abiotic urea production, and their combined effects on the proliferation of cyanobacteria leading to the great oxidation event. Urea formation was experimentally evaluated under simulated Archean conditions and cyanobacterial growth was monitored providing urea as the nitrogen source. Our findings demonstrate that urea can be produced in the Archean cyanobacterial habitats with UV-C irradiation, shedding light on the controversy regarding the evolution of nitrogen-fixing enzymes in primitive cyanobacteria. We propose that environmental conditions in the early Archean, characterized by elevated urea and nickel concentration, may have hindered cyanobacterial expansion, contributing to the delay between the evolution of oxygenic photosynthesis and the onset of the great oxidation event.

kn-title=Synthesis and biochemical characterization of naphthoquinone derivatives targeting bacterial histidine kinases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Waldiomycin is an inhibitor of histidine kinases (HKs). Although most HK inhibitors target the ATP-binding region, waldiomycin binds to the intracellular dimerization domain (DHp domain) with its naphthoquinone moiety presumed to interact with the conserved H-box region. To further develop inhibitors targeting the H-box, various 2-aminonaphthoquinones with cyclic, aliphatic, or aromatic amino groups and naphtho [2,3-d] isoxazole-4,9-diones were synthesized. These compounds were tested for their inhibitory activity (IC50) against WalK, an essential HK for Bacillus subtilis growth, and their minimum inhibitory concentrations (MIC) against B. subtilis. As a result, 11 novel HK inhibitors were obtained as naphthoquinone derivatives (IC50: 12.6–305 µM, MIC: 0.5–128 µg ml−1). The effect of representative compounds on the expression of WalK/WalR regulated genes in B. subtilis was investigated. Four naphthoquinone derivatives induced the expression of iseA (formerly yoeB), whose expression is negatively regulated by the WalK/WalR system. This suggests that these compounds inhibit WalK in B. subtilis cells, resulting in antibacterial activity. Affinity selection/mass spectrometry analysis was performed to identify whether these naphthoquinone derivatives interact with WalK in a manner similar to waldiomycin. Three compounds were found to competitively inhibit the binding of waldiomycin to WalK, suggesting that they bind to the H-box region conserved in HKs and inhibit HK activity.

kn-title=Dual roles of suberin deposition at the endodermal Casparian strip in manganese uptake of rice
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Rice roots are characterized by having two Casparian strips (CSs) at the exodermis and endodermis, where transporters for mineral nutrients are expressed. However, the exact role of the CS in expression of the transporters and subsequent nutrient uptake is poorly understood. Here, we first investigated the role of the CS in manganese (Mn) uptake by using a rice mutant (oscasp1) defective in formation of the endodermal CS. Knockout of OsCASP1 resulted in decreased Mn uptake under limited Mn conditions, but increased Mn uptake at high Mn concentration. Immunostaining revealed that knockout of OsCASP1 did not affect the cell specificity of localization of two transporters (OsNramp5 and OsMTP9) required for Mn uptake, but decreased the protein abundance of these transporters at the endodermis regardless of Mn concentrations tested. Furthermore, we found that overaccumulation of suberin at the endodermis of the mutants suppressed the expression of two transporters; the expression of the two transporters was only observed in the endodermal cells without suberin deposition, but not in the cells with suberin deposition. Taken together, our results indicate that there are two roles for the CS in Mn uptake; maintaining normal expression of the transporters at limited Mn concentration and preventing Mn diffusion to the stele at high Mn concentration.

kn-title=Electrostatically‐Driven Collapse of Polyelectrolytes: The Role of the Solvent's Dielectric Constant
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We experimentally confirm a longstanding theoretical prediction of counterion-induced
polyelectrolyte collapse in low dielectric media. The scattering behavior of polystyrene sulfonate in different solvents with dielectric permittivities in the range of ε ≃ 12 − 180 is investigated. For high and intermediate ε media, typical polyelectrolyte behavior is observed: the correlation length (ξ) scales with concentration (c) as ξ ∼ c−1∕2, as predicted by various theories. When the dielectric constant of the solvent decreases below ≃ 22, a scaling of ξ ∼ c−1∕3, characteristic of partially collapsed polyelectrolytes, is observed. For these solvents, the correlation peak disappears at high concentrations. Interestingly, polyelectrolyte collapse is observed under both solvophilic and solvophobic conditions, supporting the existence of attractive electrostatic interactions. These results are in qualitative agreement with theoretical predictions which expect chain collapse in low dielectric media due to the influence of condensed counterions, either via dipolar attraction and/or charge-correlation-induced attractions.

kn-title=Investigating the fate of Zirconium-89 labelled antibody in cynomolgus macaques
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Preclinical pharmacokinetic studies of therapeutic antibodies in non-human primates are desired because of the difficulty in extrapolating ADME data from animal models to humans. We evaluated the pharmacokinetics of 89Zr (Zirconium-89) -labelled anti-KLH human IgG and its metabolites to confirm their non-specific/physiological accumulation in healthy cynomolgus macaques. The anti-KLH antibody was used as a negative control, ensuring that the observed distribution reflected general IgG behavior rather than antigen-specific accumulation. This provides a valuable reference for comparing the biodistribution of targeted antibodies.
Methods: Selected IgG was conjugated to desferrioxamine (DFO), labelled with 89Zr, and injected into healthy cynomolgus macaques. PET/CT images at the whole-body level were acquired at different time points, and standard uptake values (SUV) in regions of interest, such as the heart, liver, spleen, kidneys, bone, and muscles, were calculated. The distribution of a shortened antibody variant, 89Zr-labelled Fab, as well as that of [89Zr]Zr-DFO and [89Zr]Zr-oxalate, the expected metabolites of 89Zr- labelled IgG, was also assessed.
Results: After 89Zr-labelled IgG injection, the SUV in the heart, vertebral body, and muscle decreased, in line with the 89Zr concentration decrease in the circulation, whereas radioactivity increased over time in the kidneys and liver. Autoradiography of the renal sections indicated that most of the 89Zr- labelled IgG radioactivity accumulated in the renal cortex. Relatively high accumulation in the kidneys was also observed in 89Zr- labelled Fab-injected macaques, and renal autoradiographs of these animals showed that the renal cortex was the preferred accumulation site. However, [89Zr]Zr-DFO was rapidly excreted into the urine, whereas [89Zr]Zr-oxalate was highly accumulated in the epiphysis of the long bones and vertebral body.
Conclusion: In the non-human primate cynomolgus macaque, 89Zr- labelled IgG accumulated in the kidneys and the liver. However, [89Zr]Zr-DFO and 89Zr did not accumulate in these organs. This preclinical pharmacokinetic study performed with human IgG in a non-human primate model using PET is of great significance as it sheds light on the basic fate and distribution of 89Zr- labelled IgG.

kn-abstract=While the continuous development of advanced bioprinting technologies is under fervent study, enhancing the regenerative potential of hydrogel-based constructs using external stimuli for wound dressing has yet to be tackled. Fibroblasts play a significant role in wound healing and tissue implants at different stages, including extracellular matrix production, collagen synthesis, and wound and tissue remodeling. This study explores the synergistic interplay between photothermal activity and nanomaterial-mediated cell proliferation. The use of different graphene-based materials (GBM) in the development of photoactive bioinks is investigated. In particular, we report the creation of a skin-inspired dressing for wound healing and regenerative medicine. Three distinct GBM, namely, graphene oxide (GO), reduced graphene oxide (rGO), and graphene platelets (GP), were rigorously characterized, and their photothermal capabilities were elucidated. Our investigations revealed that rGO exhibited the highest photothermal efficiency and antibacterial properties when irradiated, even at a concentration as low as 0.05 mg/mL, without compromising human fibroblast viability. Alginate-based bioinks alongside human fibroblasts were employed for the bioprinting with rGO. The scaffold did not affect the survival of fibroblasts for 3 days after bioprinting, as cell viability was not affected. Remarkably, the inclusion of rGO did not compromise the printability of the hydrogel, ensuring the successful fabrication of complex constructs. Furthermore, the presence of rGO in the final scaffold continued to provide the benefits of photothermal antimicrobial therapy without detrimentally affecting fibroblast growth. This outcome underscores the potential of rGO-enhanced hydrogels in tissue engineering and regenerative medicine applications. Our findings hold promise for developing game-changer strategies in 4D bioprinting to create smart and functional tissue constructs with high fibroblast proliferation and promising therapeutic capabilities in drug delivery and bactericidal skin-inspired dressings.

kn-title=A low-cost dpMIG-seq method for elucidating complex inheritance in polysomic crops: a case study in tetraploid blueberry
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Next-generation sequencing (NGS) library construction often requires high-quality DNA extraction, precise adjustment of DNA concentration, and restriction enzyme digestion to reduce genome complexity, which results in increased time and cost in sample preparation and processing. To address these challenges, a PCR-based method for rapid NGS library preparation, named dpMIG-seq, has been developed and proven effective for high-throughput genotyping. However, the application of dpMIG-seq has been limited to diploid and polyploid species with disomic inheritance. In this study, we obtained genome-wide single nucleotide polymorphism (SNP) markers for tetraploid blueberry to evaluate genotyping and downstream analysis outcomes. Comparison of genotyping qualities inferred across samples with different DNA concentrations and multiple bioinformatics approaches revealed high accuracy and reproducibility of dpMIG-seq-based genotyping, with Pearson's correlation coefficients between replicates in the range of 0.91 to 0.98. Furthermore, we demonstrated that dpMIG-seq enables accurate genotyping of samples with low DNA concentrations. Subsequently, we applied dpMIG-seq to a tetraploid F1 population to examine the inheritance probability of parental alleles. Pairing configuration analysis supported the random meiotic pairing of homologous chromosomes on a genome-wide level. On the other hand, preferential pairing was observed on chr-11, suggesting that there may be an exception to the random pairing. Genotypic data suggested quadrivalent formation within the population, although the frequency of quadrivalent formation varied by chromosome and cultivar. Collectively, the results confirmed applicability of dpMIG-seq for allele dosage genotyping and are expected to catalyze the adoption of this cost-effective and rapid genotyping technology in polyploid studies.

kn-title=Inhibitory Effects of Vandetanib on Catecholamine Synthesis in Rat Pheochromocytoma PC12 Cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Gain-of-function gene alterations in rearranged during transfection (RET), a receptor tyrosine kinase, are observed in both sporadic and hereditary medullary thyroid cancers (MTCs) and pheochromocytomas and paragangliomas (PPGLs). Several tyrosine kinase inhibitors (TKIs) that target RET have been proven to be effective on MTCs and PCCs. Recently, TKIs, namely, sunitinib and selpercatinib, which were clinically used to target PPGLs, have been reported to decrease catecholamine levels without reducing tumor size. Our clinical case of metastatic medullary thyroid cancer, which is associated with RET mutations undergoing treatment with vandetanib, also suggests that vandetanib can decrease catecholamine levels. Therefore, we investigated the effect of vandetanib, a representative multi-targeted TKI for RET-related MTC, on cell proliferation and catecholamine synthesis in rat pheochromocytoma PC12 cells. Vandetanib reduced viable cells in a concentration-dependent manner. The dopamine and noradrenaline levels of the cell lysate were reduced in a concentration-dependent manner. They also decreased more prominently at lower concentrations of vandetanib compared to the inhibition of cell proliferation. The RNA knockdown study of Ret revealed that this inhibitory effect on catecholamine synthesis is mainly mediated by the suppression of RET signaling. Next, we focused on two signaling pathways downstream of RET, namely, ERK and AKT signaling. Treatment with vandetanib reduced both ERK and AKT phosphorylation in PC12 cells. Moreover, both an MEK inhibitor U0126 and a PI3K/AKT inhibitor LY294002 suppressed catecholamine synthesis without decreasing viable cells. This study in rat pheochromocytoma PC12 cells reveals the direct inhibitory effects of vandetanib on catecholamine synthesis via the suppression of RET-ERK and RET-AKT signaling.

kn-title=A meta-linked isomer of ITIC: influence of aggregation patterns on open-circuit voltage in organic solar cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Improving the open-circuit voltage (VOC) of organic solar cells (OSCs) remains an important challenge. While it is known that the energy levels at the donor/acceptor (D/A) interface affect the VOC, the impact of aggregation patterns on the energy levels at the D/A interface has not been fully elucidated. Herein, we focus on ITIC, a widely used acceptor in OSCs, and designed a meta-linked isomer of ITIC (referred to as im-ITIC) to alter molecular symmetry and modify substitution arrangements. Concentration-dependent 1H NMR spectra revealed that im-ITIC shows stronger aggregation behavior in solution. Single-crystal X-ray analysis showed that im-ITIC forms both tail-to-tail (J-aggregation) and face-to-face (H-aggregation) stacking modes, whereas ITIC exclusively forms tail-to-tail stacking. OSCs based on PBDB-T:im-ITIC showed a high VOC value of 1.02 V, which is 0.12 V higher than that of those based on PBDB-T:ITIC. Time-resolved infrared measurements revealed the lifetime of free electrons for the pristine and blend films. The energy levels of the charge transfer state (ECT) for PBDB-T:im-ITIC- and PBDB-T:ITIC OSCs were determined to be 1.57 and 1.39 eV, respectively, correlating with the VOC values. Theoretical calculations indicated that pronounced H-aggregation in im-ITIC increases the ECT compared with J-aggregation, contributing to the improved VOC. This study underscores the critical impact of molecular aggregation patterns on energy alignment and VOC enhancement, offering insights into molecular design for achieving high VOC in OSCs.

kn-title=Analysis of the effect of permeant solutes on the hydraulic resistance of the plasma membrane in cells of Chara corallina
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In the cells of Chara corallina, permeant monohydric alcohols including methanol, ethanol and 1-propanol increased the hydraulic resistance of the membrane (Lpm−1). We found that the relative value of the hydraulic resistance (rLpm−1) was linearly dependent on the concentration (Cs) of the alcohol. The relationship is expressed in the equation: rLpm−1 = ρmCs + 1, where ρm is the hydraulic resistance modifier coefficient of the membrane. Ye et al. (2004) showed that membrane-permeant glycol ethers also increased Lp−1. We used their data to estimate Lpm−1 and rLpm−1. The values of rLpm−1 fit the above relation we found for alcohols. When we plotted the ρm values of all the permeant alcohols and glycol ethers against their molecular weights (MW), we obtained a linear curve with a slope of 0.014 M−1/MW and with a correlation coefficient of 0.99. We analyzed the influence of the permeant solutes on the relative hydraulic resistance of the membrane (rLpm−1) as a function of the external (π0) and internal (πi) osmotic pressures. The analysis showed that the hydraulic resistance modifier coefficients (ρm) were linearly related to the MW of the permeant solutes with a slope of 0.012 M−1/MW and with a correlation coefficient of 0.84. The linear relationship between the effects of permeating solutes on the hydraulic resistance modifier coefficient (ρm) and the MW can be explained in terms of the effect of the effective osmotic pressure on the hydraulic conductivity of water channels. The result of the analysis suggests that the osmotic pressure and not the size of the permeant solute as proposed by (Ye et al., J Exp Bot 55:449–461, 2004) is the decisive factor in a solute’s influence on hydraulic conductivity. Thus, characean water channels (aquaporins) respond to permeant solutes with essentially the same mechanism as to impermeant solutes.

kn-title=CNGC2 Negatively Regulates Stomatal Closure and Is Not Required for flg22- and H2O2-Induced Guard Cell [Ca2+]cyt Elevation in Arabidopsis thaliana
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In guard cells, cytosolic Ca2+ acts as a second messenger that mediates abscisic acid (ABA)- and pathogen-associated molecular pattern (PAMP)-induced stomatal closure. It was reported that Arabidopsis cyclic nucleotide-gated ion channel 2 (CNGC2) functions as hydrogen peroxide (H2O2)- and PAMP-activated Ca2+-permeable channels at the plasma membrane of mesophyll cells and mediates Ca2+-dependent PAMP-triggered immunity. In this study, we examined the role of CNGC2 in the regulation of stomatal movement because CNGC2 is also expressed in guard cells. We found that stomata of the CNGC2 disruption mutant cngc2-3 are constitutively closed even in the absence of ABA or the flagellar-derived PAMP, flg22. Consistently, leaf temperatures of the cngc2-3 mutant were higher than those of wild-type (WT) plants. The stomatal phenotype of the cngc2-3 mutant was restored by complementation with wild-type CNGC2 under the control of the guard cell preferential promoter, pGC1. Elevation of cytosolic free Ca2+ concentration in guard cells induced by flg22 and H2O2 remained intact in the cngc2-3 mutant. The introduction of the ost1-3 mutation into the cngc2-3 background did not alter the stomatal phenotype. However, the stomatal phenotype of the cngc2-3 mutant was successfully rescued in the double disruption mutant cngc2-3aba2-2. Taken together, these results suggest that CNGC2 negatively regulates stomatal closure response and does not function as flg22– and H2O2-activated Ca2+ channels in guard cells. Though CNGC2 is responsive for H2O2- and flg22-induced [Ca2+]cyt elevation in mesophyll cells, the involvement of CNGC2 in the response to H2O2 and flg22 in guard cells is questionable.

kn-abstract=In this study, we developed microfluidic paper-based analytical devices (μPADs) for the determination of antioxidant vitamins. The proposed μPADs utilize the reduction of metal ions by hydrophilic and hydrophobic antioxidant vitamins, which is followed by colorimetric reactions with chelating reagents. Hydrophilic vitamin C reduces Fe(III) to Fe(II) and forms a stable Fe(II)-bathophenanthroline complex in an aqueous solution. By contrast, this complex is unstable in organic solvents, and hydrophobic vitamin E requires Fe(III) and bathophenanthroline to be replaced with Cu(II) and bathocuproine. In these results, the relationship between the logarithm of a vitamin's concentration and its color intensity was linear and ranged from 4.4 to 35 mg L−1 for ascorbic acid and 50–200 mg L−1 for α-tocopherol. The limits of detection, estimated from the standard deviation of blank samples, were 3.1 mg L−1 for ascorbic acid and either 27 mg L−1 (in hexane) or 48 mg L−1 (in ethanol) for α-tocopherol. The proposed method was used to quantify vitamin C in bell peppers, mandarin oranges, kiwifruit, and lemons, as well as vitamin E in almonds, almond milk, and dietary supplements. The results demonstrate the effectiveness of these μPADs for the practical analysis of antioxidant vitamins in food samples.

en-abstract=
kn-abstract=The granulation process of a slurry droplet containing a water-soluble polymer in a spray dryer is investigated. Although there have been many studies on the drying behavior of a single-component slurry droplet, there have been few reports for a multicomponent slurry droplet. This is due to the complexity and difficulty in evaluating the drying behavior of a multicomponent slurry droplet. Therefore, for the production of granules from multicomponent materials by a spray dryer, its operating conditions are usually determined by trial and error. To optimize the practical granule production process, the drying behavior of multicomponent slurry droplets should be studied. In this study, the drying behavior of a silica slurry droplet containing polyvinyl alcohol (PVA) is investigated. The drying behavior of a droplet suspended on the tip of a needle was observed. The effect of the volume fraction of PVA on the drying behavior and the morphology of a dried granule is studied. The effect of drying condition on the granule formation process is also investigated. As a result, the structure of dried granules was strongly influenced by PVA concentration. Segregation of PVA in the dried granules was observed. Based on the results, the drying process diagram is presented.

kn-title=Clinical Characteristics of Vitamin D Deficiency Detected in Long COVID Patients During the Omicron Phase
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: To characterize the clinical significance of vitamin D deficiency (VDD) detected in long COVID, a retrospective observational study was performed for outpatients who visited our clinic during the period from May 2024 to November 2024. Methods: Clinical trends in long COVID patients diagnosed with VDD who showed serum concentrations of 25-hydroxyvitamin D (25-OHD) lower than 20 ng/mL were compared with those in long COVID patients in a non-deficient vitamin D (NDD) group. Results: Of 126 patients with long COVID, 97 patients (female: 50) who had been infected during the Omicron phase were included. Sixty-six patients (68%) were classified in the VDD group. The median serum concentrations of 25-OHD were 14.8 ng/mL in the VDD group and 22.9 ng/mL in the NDD group. There were no significant differences between the two groups in terms of age, gender, BMI, severity of COVID-19, period after infection and vaccination history. Although the levels of serum calcium and phosphate were not significantly different between the two groups, the percentages of patients in the VDD group who complained of dizziness, memory impairment, palpitation and appetite loss were larger than those in the NDD group. Of note, the patients who complained of palpitation showed significantly lower concentrations of serum 25-OHD than those in the patients without palpitation (median: 11.9 vs. 17.3 ng/mL). Moreover, patients in the VDD group had significantly higher scores for physical and mental fatigue as well as higher scores for depressive symptoms. Conclusions: Collectively, VDD is involved in clinical manifestations of long COVID, particularly symptoms of palpitation, fatigue and depression.

kn-title=Unraveling the Molecular Mechanism of Transient Multilamellar Formation in Ethanol-Modified Vesicle Solutions
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A recent microfluidic-based small-angle X-ray scattering (SAXS) measurement intriguingly suggested the transient formation of multilamellar structures during the mixing of unilamellar vesicles with ethanol in an aqueous solution. This study explores a possible molecular mechanism underlying this phenomenon, primarily through coarse-grained molecular dynamics (CG-MD) simulations. We first examined lipid aggregate morphology as a function of ethanol concentration in an aqueous solution. Even though vesicles were observed in pure aqueous solution, increasing ethanol concentrations led to more frequent pore formation in vesicular membranes. At ethanol concentrations above 52%, vesicles destabilized and transformed into worm-like micelles. We hypothesized that the transient multilamellar structures might arise from vesicle stacking due to variations in the effective interactions between vesicles. However, a series of potential of mean force (PMF) calculations consistently showed repulsive interactions between vesicles, regardless of ethanol concentration, ruling out this possibility. In contrast, once lipid aggregates transformed into worm-like micelles, the PMF barrier between them dropped (∼5kBT), promoting fusion. Our CG-MD simulations further demonstrated that lipid aggregates (micelles) readily fused and grew in high ethanol concentrations. Upon subsequent exposure to lower ethanol levels, these enlarged aggregates reorganized into vesicles with internal lamellar structure─multilamellar vesicles. These findings suggest that the heterogeneous mixing of unilamellar vesicular solutions with ethanol in a microfluidic device plays a key role in the emergence of transient multilamellar structures.

kn-title=Stability and water solubility of calcium ferrite-type aluminum-rich phase: implications for deep water cycle caused by subducting basaltic crusts
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The subducting crustal materials serve as a crucial channel for transporting water to the lower mantle. Recent experimental studies suggest that crustal materials such as basaltic crust can be a main water carrier and reservoir playing an important role on water cycling in the lower mantle. Despite being a primary mineral in crustal materials, the water solubility of calcium ferrite-type (CF) phase and its stability are unclear yet. A recent phase relation study of hydrous basalts showed Na-depletion in lower-mantle minerals, suggesting the presence of fluid possibly with high Na concentration and the absence of CF phase along the low-temperature slab geotherms, where Al-rich hydrous phase H and ferropericlase appear instead. These phases could consequently produce Na-depleted CF phase when reaching the dehydration temperature of Al-rich hydrous phase H. In this study, we investigated the stability and water solubility of CF-type MgAl2O4, which is a main CF component in a hydrous basalt, in water-bearing systems at 26–32 GPa and 1200–1900 °C using a Kawai-type multi-anvil press. Our results indicate that the stability of the CF phase is strongly influenced by water content in the system. Water contents of recovered CF phases estimated by Fourier-transform infrared spectroscopy show a limited variation between 73 and 87 ppm wt at a pressure of 26 GPa and temperatures of 1500–1900 °C. We suggest that CF phase could not be a primary water carrier at lower mantle depths. This emphasizes contributions of hydrous aluminous silica minerals to Earth’s deep water cycling and heterogeneous structures in the lower mantle due to the strong water partitioning to this phase compared with other constituent minerals.

kn-title=Using a microfluidic paper-based analytical device and solid-phase extraction to determine phosphate concentration
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Phosphate is an essential nutrient, but in high concentrations it contributes to water pollution. Traditional methods for phosphate measurement, such as absorption spectrophotometry and ion chromatography, require expensive equipment and skilled operators. This study introduces a microfluidic paper-based analytical device (μPAD) that is designed to accomplish field-based, low-concentration phosphate measurements. This μPAD utilizes colorimetric detection based on the molybdenum blue method. Herein, we describe how the conditions were optimized in terms of design and sensitivity by adjusting reagent concentrations, paper thickness, and the time frames for sample introduction, and reaction. The operation consists of simply dipping the μPAD into a sample, capturing images in a home-made photo studio box, and processing the images with ImageJ software to measure RGB intensity. An additional preconcentration step involves solid-phase extraction with an anion exchange resin that achieves a 10-fold enrichment, which enables detection that ranges from 0.05 to 1 mg L−1 with a detection limit of 0.089 mg L−1 and a quantification limit of 0.269 mg L−1. The replicated measurements showed good reproducibility both intraday and interday (five different days) as 4.7 % and 3.0 % of relative standard deviations, respectively. After storage in a refrigerator for as long as 26 days, this μPAD delivered stable and accurate results for real-world samples of natural water, soil, and toothpaste. The results produced using this system correlate well with those produced via spectrophotometry. This μPAD-based method is a cost-effective, portable, rapid, and simple approach that allows relatively unskilled operators to monitor phosphate concentrations in field applications.

kn-title=Novel method of leukocytapheresis using a highly concentrated sodium citrate solution alternative to acid citrate dextrose solution A
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Large-volume leukocytapheresis is time consuming. The upper limit of the inlet flow rate is determined by the inlet: anticoagulant (AC) ratio and can be changed by combining the AC with heparin. Here, we devised a protocol to increase the AC ratio using a highly concentrated sodium citrate solution without heparin.
Study Design and Methods: We collected data from 40 consecutive apheresis procedures performed using the Spectra Optia system on 40 donors for allogeneic peripheral blood stem cells between June 2022 and June 2023. We used AC containing 2.2% sodium citrate (normal concentrated sodium citrate [NSC]) and 5.32% sodium citrate (highly concentrated sodium citrate [HSC]). The AC ratios were set to 12:1 and 24:1 for the NSC and HSC, respectively.
Results: The processed volume was not different; the maximum inlet flow rate increased, the total processing time was reduced, the AC solution used was reduced, and the product volume was reduced in the HSC group, compared to the NSC group. Although the CD34+ cell CE2 was reduced in the HSC group, no difference was observed in the number of collected CD34+ cells. The incidences of citrate-related reactions were similar.
Discussion: We propose a novel leukocytapheresis method using HSC that shortens the procedure time and reduces the amount of AC solution used compared to the conventional method

kn-abstract=This study investigated the effects of varying concentrations of two distinct silane agents, 8-methacryloxyoctyl trimethoxy silane (8-MOTS) and 3-methacryloxypropyl trimethoxy silane (γ-MPTS), on their initial bonding efficacy to feldspathic ceramic (FC), lithium disilicate glass-ceramic (LD) and polymer-infiltrated ceramic (PIC) specimens, in 10% increments for concentrations ranging from 10% to 40%. Shear bond strengths between the ceramic substrates and the luting material were assessed following 24 h incubation in distilled water. For FC, the median value of shear bond strength peaked at 20% of γ-MPTS (7.4 MPa), while 8-MOTS exhibited a concentration-dependent increase, reaching its highest value at 40% (13.1 MPa). For LD, γ-MPTS above 10% yielded similar strength median values (10.2 MPa), whereas 8-MOTS at 30% (15.8 MPa) and 40% (13.4 MPa) yielded higher strength values than at 10% (2.9 MPa) and 20% (4.1 MPa), with the highest median value exhibited at 30%. For PIC, both γ-MPTS and 8-MOTS demonstrated similarly low bond strength values which were not significantly different from the non-silane-treated specimens. When applied on silica-based FC and LD, silane revealed a concentration-dependent bonding effect, with 8-MOTS exhibiting superior bond strength to γ-MPTS. However, PIC, characterized by a high inorganic filler content, demonstrated limited bondability with both silanes.

kn-title=Spray-drying of polymer solutions across a broad concentration range and the subsequent formation of a few micro- ∼nano-meter sized fibers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Spray drying is a widely utilized technique for the concentration and fine particulation of dried products. This study demonstrated that a versatile spray dryer, equipped with a two-fluid nozzle atomizer, can convert polymer solutions into nanoscale fibers by manipulating the conditions of the polymer solutions. The polymers employed in this research included polyvinylpyrrolidones (Mw 24.5 k to 60 kDa), dextrans (70 k to 450–650 kDa), pullulan, gum Arabic, Eudragit and agar, with methanol and water serving as solvents. Various combinations of polymers and solvents were subjected to spray drying at polymer concentrations ranging from 5 to 1000 g/L. Scanning electron microscopy analyses of the spray-dried samples indicated that the products transitioned from micrometer-sized particles to sub-micrometer fibers in several instances when the polymer concentrations exceeded specific threshold levels. The investigation also explored the relationship between these threshold concentrations and the surface tension and viscosity of the polymer solutions.

kn-title=Effect of calcium supplementation on bone deformity and histopathological findings of skin papules in a pediatric patient with vitamin D–dependent rickets type 2A: A case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Vitamin D–dependent rickets type 2A (VDDR2A) is an autosomal recessive disease caused by pathogenic variants of the vitamin D receptor (VDR) gene. VDDR2A rickets are usually resistant to native or active vitamin D treatment because of impaired active calcium absorption against the calcium concentration gradient, which is a ligand-dependent VDR action in the small intestine. Alopecia due to an impaired skin follicular cycle is occasionally observed in patients with VDDR2A. Among the pathogenic VDR variants, most in the DNA-binding domain and some in the ligand-binding domain, which affect the dimerization of VDR with the retinoic X receptor, are associated with alopecia. Herein, we report a case of VDDR2A caused by compound heterozygous pathogenic variants of the DNA-binding domain of VDR. Active vitamin D treatment did not ameliorate genu varum, rachitic changes in the roentgenogram, or abnormal laboratory findings. However, oral administration of calcium lactate dramatically improved these findings. The patient also experienced hair loss at two months of age and multiple papules on the skin at two yr of age, which did not improve with vitamin D or calcium supplementation. We also report the histopathological findings of skin papules in this patient.

kn-title=Effects of Trehalose on Halitosis: A Randomized Cross-Over Clinical Trial
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background/Objectives: Halitosis is a condition characterized by an unpleasant malodor. Intra-oral halitosis is caused by volatile sulfur compounds (VSCs) and can be associated with oral dryness. Trehalose is one of the materials used to relieve oral dryness. The aim of the present study was to investigate the effect of trehalose on halitosis. Methods: This prospective, double-blinded, placebo-controlled, cross-over study enrolled volunteers from Okayama University Hospital. The participants were randomly divided into two groups, with one group receiving trehalose (a 10% trehalose solution) and the other receiving a placebo (distilled water) in a 1:1 allocation. The primary study outcome was the subjective organoleptic test. The secondary outcomes were the concentrations of the VSCs, which were measured using a portable gas chromatography device, and the oral moisture status, which was measured using an oral moisture meter. The planned sample size was 10 participants based on the previous study. Results: The final intention-to-treat analysis was performed using the data from 9 participants. After applying 10% trehalose as an oral spray, the organoleptic score decreased in a time-dependent manner. However, no significant differences were seen between the trehalose and placebo groups. In terms of secondary outcomes, the oral moisture levels increased immediately after the trehalose spray application, and significant differences in the amount of change from the baseline were seen between the trehalose and placebo groups (p = 0.047). No significant differences were seen in any of the other variables (p > 0.05). Conclusions: We could not identify any positive effects on halitosis from a one-time 10% trehalose application as an oral spray in this prospective, double-blinded, placebo-controlled, cross-over study. However, the trehalose application immediately improved the oral moisture levels and was useful for treating oral dryness.

en-abstract= In this study, we summarized research trends related to the educational needs and support of children with cancer from the perspectives of “learning,” “self-management,” “interpersonal,” “psychological,” and “collaboration,”. In terms of learning, the study showed that experiential learning and distance education are solutions to the problem of delayed learning due to prolonged absence from school and poor concentration during treatment. Next, in self-management, it is important to educate affected children so that they can fully understand the disease and treatment. In addition, in terms of interpersonal support, it is difficult for the affected patients to build relationships with friends, but providing opportunities for interaction is expected to contribute to the improvement of interpersonal relationships. In terms of psychological support, the anxiety associated with treatment is a major psychological burden for the affected children, and the understanding of their friends and the intervention of university student volunteers are effective in helping them achieve psychological stability. Finally, the lack of cooperation between medical institutions and schools was highlighted as a deficiency in the support system, which needs to be strengthened. In the future, these support measures should be empirically verified to establish a sustainable support system.
kn-abstract= 本研究は、小児がん患児の教育的支援に関する研究の動向を明らかにし、今後の課題とその解決策を提起することを目的とした。「学習」、「自己管理」、「対人」、「心理」、「連携」の5つの視点から分析を行った。学習支援について、治療に伴う学習の遅れや集中力の低下に対し、個別の教育支援計画や体験的な学習、および遠隔教育の実施に期待されていた。自己管理支援では、患児が自身の病状や治療による副作用を理解し、自立的に管理できる能力を育成することが求められていた。対人支援について、患児の長期入院により、友人関係の構築が困難になり、入院中や復学後のコミュニケーションの支援が重要であることが確認された。心理支援においては、周囲への効果的ながん教育や大学生ボランティアによる支援が、患児の心理的安定を促すことが示された。最後に、学校と医療機関、保護者の連携不足が指摘されており、連携ツールの開発が求められている。

en-title=Survival, Creation, and Disappearance of Manufacturing Firms in the First Stage of Regional Revitalization
kn-title=地方創生第1期における製造事業所の存続,発生,消失
en-subtitle=

en-abstract= In many local municipalities, in addition to revitalizing existing businesses and creating new businesses, attracting manufacturing plants remains an important policy for regional development. Today, unlike the attraction of heavy, large-scale industries during the period of high economic growth, there is a trend to attract companies by making the most of the region's advantages. Although the job creation effect has become smaller than in the past, many manufacturing industries remain positioned as core industries in the region. During the first period of regional revitalization, we identify what manufacturing firms have disappeared, withdrawn, appeared, or survived in what regions, and analyze the factors behind those.
Comparing manufacturing firms in 2014 and 2019, the average of value-added and the distribution of that shows that manufacturing firms that existed in both 2014 and 2019 had the highest labor productivity. The next highest was manufacturing firms that existed in 2019, and the lowest was manufacturing firms that existed in 2014 but did not exist in 2019. In addition, the results of the logit analysis suggest that manufacturing firms with high productivity and large size tend not to disappear, and that manufacturing firms with a high degree of urbanization tend to disappear. On the other hand, a regression analysis at the city/town/village level using industry concentration by industry and urban concentration measured by population size as explanatory variables showed a positive effect on the number of manufacturing firms that had been established.
kn-abstract= 地方に位置する多くの自治体においては,従来からある事業所の活性化や新規事業所の誕生に加えて,製造工場の誘致は地域振興にとっていまも重要な政策となっている。今日,高度経済成長期における重厚長大型の産業の誘致とは異なり,地域優位性をできるだけ活用した企業誘致の傾向になっている。雇用創出効果は昔に比べて小さくなっているとはいえ,製造業の多くにおいて,地域の基盤産業としての位置づけは残っている。第1期の地方創生の期間で,どのような地域において,どのような製造工場が消失,撤退や出現,存続しているのかを識別し,それらの要因を分析する。
2014年と2019年の事業所の比較において,付加価値生産性の平均と分布を見ると2014年,2019年ともに存在する事業所の労働生産性が最も高い。次いで高いのが2019年に存在する事業所で,最も低かったのが2014年には存在したが2019年には存在していない事業所であった。またロジット分析の結果から,生産性が高く事業所規模が大きいと消滅しない傾向があり,また都市化の程度が高いと消滅傾向にあることが推定された。他方,発生した製造事業所について,産業別に同業種集積と人口規模で測った都市集積を説明変数とした市町村単位の回帰分析からは正の効果が示された。

kn-title=Efficacy of Oral Intake of Hydrogen-Rich Jelly Intake on Gingival Inflammation: A Double-Blind, Placebo-Controlled and Exploratory Randomized Clinical Trial
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background/Objectives: Initiation and progression of periodontal disease include oxidative stress. Systemic application of antioxidants may provide clinical benefits against periodontal disease including gingivitis. Recently, a jelly containing a high concentration of hydrogen (40 ppm) was developed. We hypothesized that oral intake of this hydrogen-rich jelly may be safe and effective on gingivitis. This clinical trial was designed to investigate the safety and efficacy of oral intake of hydrogen-rich jelly against gingival inflammation. Methods: Participants with gingivitis were instructed to orally ingest 30 g of hydrogen-rich jelly (experimental group) or placebo jelly (control group) three times a day for 14 consecutive days. The primary outcome of this trial was the percentage of bleeding on probing (BOP) sites. Secondary outcomes were oral parameters, serum reactive oxygen metabolites, antioxidant capacity, oxidative index, concentrations of cytokine (interleukin [IL]-1β, IL-6, IL-10, IL-17, and tumor necrosis factor-alpha) in gingival crevicular fluid, and adverse events. For all parameters, Mann–Whitney U test was used for comparison between experimental and control groups. Analysis of covariance, controlling for baseline periodontal inflamed surface area, was performed to evaluate the association between the effect of the hydrogen-rich jelly and gingival inflammation. Results: In the experiment and control groups, the percentage of sites with BOP and PISA significantly decreased at the end of the experiment compared to the baseline. However, no significant differences were found between groups (p > 0.05). Conclusions: Administration of hydrogen-rich jelly for 14 days decreased gingival inflammation. However, no significant differences were identified compared to the control group.

kn-title=A microfluidic paper-based analytical device that uses gelatin film to assay protease activity via time readout
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Food processing, detergents, and pharmaceuticals frequently employ proteases, which are enzymes that break the chemical bonds of both proteins and peptides. In this work, we developed a microfluidic paper-based analytical device (µPAD) for protease activity assays via time readout. To accomplish this, we folded the µPAD to form layers, then inserted a water-insoluble gelatin film between the layers of paper to form the device. Lamination helps to maintain the gelatin film between the introduction zone, which is the upper layer, and the detection channel, which is the lower layer. Proteases decompose the gelatin film when it enters the introduction zone, which then allows it to flow into the detection channel. The protease activity in the sample solution determines the time required to dissolve the gelatin film, which leads to a linear relationship between the logarithm of the protease concentration and the time required to flow the solution a specific distance on the detection channel. The µPAD was used to measure proteases in concentrations that ranged from 0.25 to 1 mg L−1 for bromelain, 2.5 to 10 mg L−1 for papain, and 1 to 8 mg L−1 for trypsin. The limits of quantification for bromelain, papain, and trypsin were 0.41, 2.7, and 9.2 mg mL−1, respectively. The relative standard deviations for bromelain were smaller than 2 % for concentrations ranging from 0.5 to 1.0 mg L−1. We compared the µPAD to a commercially available protease activity assay kit, which relies on quenching fluorescein isothiocyanate-labeled casein. Both methods demonstrated the same order of activity: bromelain > papain > trypsin. The proposed device allowed the assay of bromelain in both pineapple pulp and juice, which were stored at room temperature. When first using the proposed device, the bromelain in the pulp gradually lost its activity, while the activity of the bromelain in the juice showed no significant change for five days. The µPAD requires no analytical instruments for quality control and monitoring of the protease activity in food.

kn-title=Evaluation of the temporal behavior of fulvic acid iron in Asahi River, Okayama, Japan
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Iron is essential for biogeochemical processes in aquatic ecosystems, but its riverine concentration can be affected by environmental conditions. This study assessed weekly fulvic acid iron (FAFe) concentration at a single sampling site in Asahi River from 2022–2023 to explore the differences in the temporal scales. The objectives of this study were to evaluate the effects of physicochemical properties of the river on the concentration of FAFe, analyze the concentration of FAFe in spring, summer, autumn and winter, and assess the relationship between FAFe concentration and land use types of the watershed. The results indicated that physicochemical parameters, such as pH and surface water temperature (SWT) seemed to influence FAFe concentration (p < 0.05). Hydrological dynamics influenced FAFe concentration and transport, revealing an increasing trend during spring (p < 0.001) and summer (p = 0.05), with non-significant trends during autumn and winter (p > 0.05). FAFe exhibited a strong positive correlation with total organic carbon (TOC) (p < 0.001). Upland fields significantly influenced FAFe concentration (p < 0.01) through runoff with abundant NO3– and PO43– into the river. Thus, FAFe concentration in Asahi River was influenced by pH, SWT, TOC, hydrological regime, and agricultural runoff.

kn-title=Microfluidic fabrication of rattle shaped biopolymer microcapsules via sequential phase separation in oil droplets
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Multilayer microcapsules containing a small particle within a larger capsule have recently attracted considerable attention owing to their potential applications in diverse fields, including drug delivery, active ingredient storage, and chemical reactions. These complex capsules have been fabricated using interfacial polymerization or seeded emulsion polymerization. However, these methods often require complex and lengthy polymerization processes, limiting their utility, particularly in biopolymer systems. This study introduces a simple and efficient approach for preparing rattle-shaped cellulose acetate (CA) microcapsules through sequential phase separation in droplets. We systematically examine the effects of various preparation parameters, including the amount of co-solvent, initial droplet size, and flow rates, and reveal that the incorporation of a co-solvent-ethyl acetate (EA)- in the dispersed phase significantly impacts the microcapsule morphology. Our findings demonstrate a transition from a core-shell to a rattle-shaped structure as the EA concentration increases. Furthermore, the initial droplet diameter and flow rates influence microcapsule formation-larger droplets and reduced continuous-phase flow rates favor the development of multi-layered structures. These results indicate that the formation mechanism of these rattle-shaped microcapsules arises from the establishment of a radial solvent concentration gradient and subsequent phase separation within the droplets, driven by kinetic rather than thermodynamic factors.

kn-title=Antifouling Activity of Xylemin, Its Structural Analogs, and Related Polyamines
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Biofouling, which is the accumulation of organisms on undersea structures, poses significant global, social, and economic issues. Although organotin compounds were effective antifoulants since the 1960s, they were banned in 2008 due to their toxicity to marine life. Although tin-free alternatives have been developed, they also raise environmental concerns. This underscores the need for effective, nontoxic antifouling agents. We previously synthesized N-(4-aminobutyl)propylamine (xylemin) and its structural analogs. In this study, we assayed the antifouling activity and toxicity of xylemin, its structural analogs, and related polyamines toward cypris larvae of the barnacle Amphibalanus amphitrite. Xylemin and its Boc-protected analog exhibited antifouling activities with 50% effective concentrations (EC50) of 4.25 and 6.11 µg/mL, respectively. Four xylemin analogs did not show a settlement-inhibitory effect at a concentration of 50 µg/mL. Putrescine, spermidine, spermine, and thermospermine, which are xylemin-related polyamines, did not display antifoulant effects (EC50 > 50 µg/mL). All evaluated compounds were nontoxic at a concentration of 50 µg/mL. These findings indicate that the size and structure of the N-alkyl group are essential for the antifouling activity of xylemin. Therefore, xylemin and its analogs hold promise as nontoxic, eco-friendly antifouling agents, offering a sustainable solution to biofouling in marine environments.

kn-title=Fraglide-1 from traditional Chinese aromatic vinegar: A natural AhR antagonist for atopic dermatitis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Traditional Chinese Zhenjiang aromatic vinegar (Kozu) contains Fraglide-1 (FG1), a bioactive lactone with demonstrated peroxisome proliferator-activated receptor gamma (PPARγ) agonist and antioxidant activities. This study explored FG1's novel ability to antagonize the aryl hydrocarbon receptor (AhR) signaling pathway, which regulates artemin expression and contributes to itching and inflammation in atopic dermatitis. Through molecular docking simulations and cell-based assays in human keratinocytes, we demonstrated FG1's potent antagonistic activity against AhR signaling. FG1 effectively suppressed FICZ-induced inflammatory responses, including artemin expression, with potency (half maximal inhibitory concentration, IC50 = 5.1 μM) comparable to the synthetic antagonist StemRegenin 1 (SR1) while demonstrating a superior safety profile (median lethal concentration, LC50 > 100 μM vs. 27.5 μM for SR1). These findings expand our understanding of bioactive compounds from traditional fermented foods and their regulatory effects on AhR signaling, providing a foundation for future studies on FG1's role in modulating skin inflammation.

kn-abstract=The common green bottle fly, Lucilia sericata (Meigen) (Diptera: Calliphoridae), is a promising and useful managed pollinator for greenhouse agricultural crops. The fly can pollinate at lower and higher temperatures than European honeybee. However, management of the longevity of pollinators is important for growers using greenhouses. Previous studies using other insects showed that caffeine affects insect longevity and behaviors. For instance, European honeybee live longer and have increased memory after caffeine consumption. How caffeine affects the longevity and behavior of pollinators is worth investigating because it can affect pollinator’s behavior, extend longevity, or be an insecticide against pollinators. In the present study, therefore, the longevity and locomotion of L. sericata were investigated when they were given different caffeine concentrations. First, the longevity of L. sericata with five different caffeine concentrations was compared to the control. The results showed that higher concentrations of caffeine (2%, 1%, and 0.5%) significantly decreased the life span compared to lower concentrations (0.05% and 0.01%). Second, the locomotion activities of L. sericata were examined at those two caffeine concentrations with treated and control male and female flies utilizing a Drosophila Activity Monitor (DAM). Treatment with 0.05% caffeine dramatically reduced locomotion, but treatment of 0.01% caffeine did not. We also compared lipid concentrations of flies: flies treated with 0.05% caffeine had a lower lipid concentration compared to flies treated with 0% and 0.01% caffeine. These results indicate that caffeine had negative effects on the longevity and locomotion activities of the pollinator L. sericata in laboratory conditions.

kn-title=Photoinitiators Induce Histamine Production in Human Mast Cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Photoinitiators are used in the manufacture of many daily products, and may produce harmful effects due to their cytotoxicity. They have also been detected in human serum. Here, we investigated the histamine-producing effects in HMC-1 cells and the inflammatory cytokine release effects in RAW264 cells for four photoinitiators: 1-hydroxycyclohexyl phenyl ketone; 2-isopropylthioxanthone; methyl 2-benzoylbenzoate; and 2-methyl-4´-(methylthio)-2-morpholinopropiophenone. All four promoted histamine production in HMC-1 cells; however, they did not significantly affect the release of inflammatory cytokines in RAW264 cells. These findings suggest that these four photoinitiators induce inflammatory cytokine-independent histamine production, potentially contributing to histamine-mediated chronic inflammation in vitro.

kn-title=Mapping Surface Potential in DNA Aptamer-Neurochemical and Membrane-Ion Interactions on the SOS Substrate Using Terahertz Microscopy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this study, we utilized a terahertz chemical microscope (TCM) to map surface potential changes induced by molecular interactions on silicon-on-sapphire (SOS) substrates. By functionalizing the SOS substrate with DNA aptamers and an ion-selective membrane, we successfully detected and visualized aptamer-neurochemical complexes through the terahertz amplitude. Additionally, comparative studies of DNA aptamers in PBS buffer and artificial cerebrospinal fluid (aCSF) were performed by computational structure modeling and terahertz measurements. Beyond neurochemicals, we also investigated calcium ions, measuring their concentrations in PDMS-fabricated micro-wells using minimal sample volumes. Our results highlight the capability of TCM as a powerful, label-free, and sensitive platform for the probing and mapping of surface potential arising from molecular interactions, with broad implications for biomedical diagnostics and research.

kn-title=Reversible chemical modifications of graphene oxide for enhanced viral capture and release in water
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Detecting low concentrations of viruses in sewage water is crucial for monitoring the spread of emerging viral diseases. However, current detection methods, which involve concentrating viruses using traditional materials such as gauze or cotton, have limitations in effectively accomplishing this task. This study demonstrates that graphene oxide (GO), a two-dimensional carbon material, possesses strong viral adsorption capabilities. However, it lacks efficiency for effective viral release. Therefore, we designed a series of new GO-based materials, which exhibited a viral adsorption similar to pristine GO, while significantly enhancing their release performance by attaching alkyl chains and hydrophilic functional groups. Among the synthesized materials, 1,8-aminooctanol grafted to GO (GO-NH2C8OH) has emerged as the most promising candidate, achieving a viral release rate higher than 50 %. This superior performance can be attributed to the synergistic effect of the alkyl chain and the terminal OH group, which enhances both its affinity for viruses and water dispersibility. Furthermore, we have successfully applied GO-NH2C8OH in a new protocol for concentrating viruses from sewage wastewater. This approach has demonstrated a 200-fold increase in virus concentration, allowing PCR detection of this type of pathogens present in wastewater below the detection limit by direct analysis, underscoring its significant potential for virus surveillance.

kn-title=Resveratrol, a food-derived polyphenol, promotes Melanosomal degradation in skin fibroblasts through coordinated activation of autophagy, lysosomal, and antioxidant pathways
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Resveratrol, a polyphenol found in grapes and peanuts, is known for diverse biological activities, yet its effects on dermal hyperpigmentation (so-called dark spots) remain unexplored. We investigated resveratrol's ability to enhance melanosomal degradation in human dermal fibroblasts. At concentrations of 25-50 mu M, resveratrol increased autophagy as measured by microtubule-associated protein 1A/1B-light chain 3 (LC3)-II/LC3-I ratio and enhanced lysosomal activity as assessed by a lysosomal activity reporter system. RNA sequencing revealed upregulation of lysosomal and autophagy-related genes, including cathepsins. Furthermore, reporter assays showed resveratrol's activation of antioxidant response via nuclear factor erythroid 2-related factor 2 (NRF2)mediated, leading to upregulation of transcription factor EB/transcription factor E3 (TFEB/TFE3), master regulators of lysosomal function. In fibroblasts pre-loaded with melanosomes, resveratrol reduced melanosome content compared to control by day 3. The findings reveal the activation of interconnected autophagy, lysosomal, and antioxidant pathways by resveratrol, suggesting potential applications in functional foods targeting dermal hyperpigmentation.

kn-title=Hydronium Ions Are Less Excluded from Hydrophobic Polymer–Water Interfaces than Hydroxide Ions
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The cloud point temperatures of aqueous poly(N-isopropylacrylamide) (PNIPAM) and poly(ethylene) oxide (PEO) solutions were measured from pH 1.0 to pH 13.0 at a constant ionic strength of 100 mM. This ionic strength was reached by mixing the appropriate concentration of NaCl with either HCl or NaOH. The phase transition temperature of both polymers was nearly constant between pH 2.0 and 12.0. However, the introduction of 100 mM HCl (pH 1.0) led to an increase in the cloud point temperature, although this value was still lower than the cloud point temperature in the absence of salt. By contrast, the introduction of 100 mM NaOH (pH 13.0) caused a decrease in the cloud point temperature, both relative to adding 100 mM NaCl and adding no salt. Nuclear magnetic resonance (NMR) studies of these systems were performed below the cloud point temperature, and the chemical shifts closely tracked the corresponding changes in the phase transition temperature. Specifically, the introduction of 100 mM HCl caused the 1H chemical shift to move downfield for the CH resonances from both PNIPAM and PEO, while 100 mM NaOH caused the same resonances to move upfield. Virtually no change in the chemical shift was seen between pH 2.0 and 12.0. These results are consistent with the idea that a sufficient concentration of H3O+ led to polymer swelling compared to Na+, while substituting Cl– with OH– reduced swelling. Finally, classical all-atom molecular dynamics (MD) simulations were performed with a monomer and 5-mer corresponding to PNIPAM. The results correlated closely with the thermodynamic and spectroscopic data. The simulation showed that H3O+ ions more readily accumulated around the amide oxygen moiety on PNIPAM compared with Na+. On the other hand, OH– was more excluded from the polymer surface than Cl–. Taken together, the thermodynamic, spectroscopic, and MD simulation data revealed that H3O+ was less depleted from hydrophobic polymer/water interfaces than any of the monovalent Hofmeister metal cations or even Ca2+ and Mg2+. As such, it should be placed on the far-right side of the cationic Hofmeister series. On the other hand, OH– was excluded from the interface and could be positioned in the anionic Hofmeister series between H2PO4– and SO42–.

kn-abstract=Many patients with cholera emerge in Kolkata, India throughout the year. Such emergency indicates that cholera toxin-producing Vibrio cholerae O1 (toxigenic V. cholerae O1) are widespread in Kolkata. This suggests that the suitable conditions for replication of toxigenic V. cholerae O1 is provided in Kolkata. In previous studies, we found that the replication rate of toxigenic V. cholerae O1 is low in the low ionic aqueous solution. Then we measured the ion concentration in the environmental water of Kolkata. As a control, we measured them in Japanese environmental water. The ion concentration in the environmental water of Kolkata was significantly high. Then, we examined the survival of toxigenic V. cholerae O1 in groundwater from Kolkata and found that V. cholerae O1 survive for long time in the solution but not in the solution diluted with Milli Q water. In addition, we found that V. cholerae O1 proliferated in environmental water of Kolkata to which a small amount of nutrient was added, but did not grow in the environmental water diluted with water to which the same amount of nutrient was added. These results indicate that the environmental water from Kolkata is suitable for survival of V. cholerae O1.

kn-title=Clinical and microbiological characteristics of high-level daptomycin-resistant Corynebacterium species: A systematic scoping review
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: Corynebacterium species potentially develop high-level daptomycin resistance (HLDR) shortly after daptomycin (DAP) administration. We aimed to investigate the clinical and microbiological characteristics of HLDR Corynebacterium infections.
Methods: We first presented a clinical case accompanied by the results of a comprehensive genetic analysis of the isolate, and then performed a systematic scoping review. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews, we searched for articles with related keywords, including “Corynebacterium”, “Daptomycin", and "Resistance”, in the MEDLINE and Web of Science databases from the database inception to October 25, 2024. Clinical case reports and research articles documenting the isolation of HLDR Corynebacterium species, defined by a minimum inhibitory concentration of DAP at ≥256 μg/mL, were deemed eligible for this review.
Results: Of 80 articles screened, seven case reports detailing eight cases of HLDR Corynebacterium infections, as well as five research articles, were included. C. striatum was the most common species (7/9 cases, 77.8 %), and prosthetic device-associated infections accounted for 66.7 % of the cases. Duration of DAP administration before the emergence of HLDR isolates ranged from 5 days to 3 months; three-quarters of the cases developed within 17 days. Three HLDR isolates were genetically confirmed to have an alteration in pgsA2. The majority of the patients were treated with either glycopeptides or linezolid, with favorable outcomes. In vitro experiments confirmed that C. striatum strains acquire the HLDR phenotype at higher rates (71 %–100 %) within 24 h of incubation, compared to other Corynebacterium strains.
Conclusion: DAP monotherapy, especially for prosthetic device-associated infections, can result in the development of HLDR Corynebacterium. Additional research is warranted to investigate the clinical implications of this potentially proliferating antimicrobial resistant pathogen.

kn-title=Effects of aged microplastics on paddy soil properties and greenhouse gas emissions under laboratory aerobic conditions
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Microplastics (MPs) formed after changes in chemical or physical properties may alter soil properties, which in turn may affect microbial activities and greenhouse gas (GHG) emissions. However, few studies have focused on the effects of aged MPs changes on soil properties and greenhouse gas emissions. Therefore, we aimed to investigate the impact of MPs with different aging times on soil GHG emissions and dissolved organic carbon (DOC). Low-density polyethylene (PE) and polylactic acid (PLA) were treated with ultraviolet (UV) irradiation for 0–2 weeks. Soil was incubated with PE or PLA 1% (w/w) concentration at 60% water holding capacity (WHC) for 35 days. Emissions of nitrous oxide (N2O) and carbon dioxide (CO2) were measured on days 0, 1, 3, 5, 7, 14, 21, 28, and 35. Results showed that CO2 and N2O emissions were higher (p < 0.05) in MPs-amended treatments than those without MPs and increased with MPs age. The addition of virgin PE did not affect soil DOC content, whereas aged PE and all PLA additions significantly increased soil DOC content on day 0, probably because UV irradiation caused the degradation of MPs to smaller molecules. In addition, aged MPs addition altered DOC spectral characteristics on day 7, possibly because aged PE and PLA promote microbial decomposition of organic matter by altering soil properties. Changes in soil DOC content and specific ultraviolet absorbance (SUVA) by aged PE and PLA probably promoted the emissions of CO2 and N2O compared to virgin MPs or soil only. Our study revealed that aged PE and PLA promote GHG emissions from soil by changing DOC contents and qualities.

kn-title=Phase-dependent trends in the prevalence of myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) related to long COVID: A criteria-based retrospective study in Japan
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background
The characteristics of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) related to COVID-19 have remained uncertain. To elucidate the clinical trend of ME/CFS induced by long COVID, we examined data for patients who visited our outpatient clinic established in a university hospital during the period from Feb 2021 to July 2023.
Methods
Long COVID patients were classified into two groups, an ME/CFS group and a non-ME/CFS group, based on three diagnostic criteria.
Results
The prevalence of ME/CFS in the long COVID patients was 8.4% (62 of 739 cases; female: 51.6%) and factors related to ME/CFS were severe illness, smoking and alcohol drinking habits, and fewer vaccinations. The frequency of ME/CFS decreased from 23.9% in the Preceding period to 13.7% in the Delta-dominant period and to 3.3% in the Omicron-dominant period. Fatigue and headache were commonly frequent complaints in the ME/CFS group, and the frequency of poor concentration in the ME/CFS group was higher in the Omicron period. Serum ferritin levels were significantly higher in female patients in the ME/CFS group infected in the Preceding period. In the ME/CFS group, the proportion of patients complaining of brain fog significantly increased from 22.2% in the Preceding period to 47.9% in the Delta period and to 81.3% in the Omicron period. The percentage of patients who had received vaccination was lower in the ME/CFS group than the non-ME/CFS group over the study period, whereas there were no differences in the vaccination rate between the groups in each period.
Conclusion
The proportion of long COVID patients who developed ME/CFS strictly diagnosed by three criteria was lower among patients infected in the Omicron phase than among patients infected in the other phases, while the proportion of patients with brain fog inversely increased. Attention should be paid to the variant-dependent trends of ME/CFS triggered by long COVID (300 words).

kn-title=Risk Factors for Gangrenous Cholecystitis and the Outcomes of Early Cholecystectomy: A Retrospective Study of a Single-Center City General Hospital
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Gangrenous cholecystitis (GC) is classified as moderate acute cholecystitis according to the Tokyo Guidelines from 2018 (TG18). We evaluated the risk factors for GC and the outcomes of early cholecystectomy. A total of 136 patients who underwent emergency cholecystectomy for acute cholecystitis were retrospectively analyzed; 58 of these patients (42.6%) were diagnosed with GC (GC group) based on our retrospective pathologic diagnosis. We comparatively evaluated the patient backgrounds and surgical outcomes between the GC group and non-GC group. The GC group was significantly older and included more hypertensive patients than the non-GC group. The GC group was prescribed more antibiotics as initial treatment than the non-GC group, and they had more days between onset and surgery. The preoperative white blood cell count and C-reactive protein values were significantly higher in the GC group than in the non-GC group, and these values were predictive factors for GC. Cholecystectomy required a longer operation time and caused greater blood loss in the GC group. The GC group also had longer hospitalization times than the non-GC group; however, no significant differences were observed in terms of postoperative complications. In conclusion, gangrenous changes should be assessed when diagnosing cholecystitis, and appropriate treatment, such as surgery or drainage, should be undertaken.

kn-abstract=In the detection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), several methods have been employed, including the detection of viral ribonucleic acid (RNA), nucleocapsid (N) proteins, spike proteins, and antibodies. RNA detection, primarily through polymerase chain reaction tests, targets the viral genetic material, whereas antigen tests detect N and spike proteins to identify active infections. In addition, antibody tests are performed to measure the immune response, indicating previous exposure or vaccination. Here, we used the developed terahertz chemical microscope (TCM) to detect different concentrations of N protein in solution by immobilizing aptamers on a semiconductor substrate (sensing plate) and demonstrated that the terahertz amplitude varies as the concentration of N proteins increases, exhibiting a highly linear relationship with a coefficient of determination (R2 = 0.9881), indicating that a quantitative measurement of N proteins is achieved. By optimizing the reaction conditions, we confirmed that the amplitude of the terahertz wave was independent of the solution volume. Consequently, trace amounts (0.5 μL) of the N protein were successfully detected, and the detection process only took 10 min. Therefore, this study is expected to develop a rapid and sensitive method for the detection and observation of the SARS-CoV-2 virus at a microdetection level. It is anticipated that this research will significantly contribute to reducing the spread of novel infectious diseases in the future.

kn-title=Evaluating the activity of N-89 as an oral antimalarial drug
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Despite the recent progress in public health measures, malaria remains a troublesome disease that needs to be eradicated. It is essential to develop new antimalarial medications that are reliable and secure. This report evaluated the pharmacokinetics and antimalarial activity of 1,2,6,7-tetraoxaspiro[7.11]nonadecane (N-89) using the rodent malaria parasite Plasmodium berghei in vivo. After a single oral dose (75 mg/kg) of N-89, its pharmacokinetic parameters were measured, and t1/2 was 0.97 h, Tmax was 0.75 h, and bioavailability was 7.01%. A plasma concentration of 8.1 ng/ml of N-89 was maintained for 8 h but could not be detected at 10 h. The dose inhibiting 50% of parasite growth (ED50) and ED90 values of oral N-89 obtained following a 4-day suppressive test were 20 and 40 mg/kg, respectively. Based on the plasma concentration of N-89, we evaluated the antimalarial activity and cure effects of oral N-89 at a dose of 75 mg/kg 3 times daily for 3 consecutive days in mice harboring more than 0.5% parasitemia. In all the N-89- treated groups, the parasites were eliminated on day 5 post-treatment, and all mice recovered without a parasite recurrence for 30 days. Additionally, administering oral N-89 at a low dose of 50 mg/kg was sufficient to cure mice from day 6 without parasite recurrence. This work was the first to investigate the pharmacokinetic characteristics and antimalarial activity of N-89 as an oral drug. In the future, the following steps should be focused on developing N-89 for malaria treatments; its administration schedule and metabolic pathways should be investigated.

kn-abstract= As a preliminary step to conducting a self-organizing simulation of the agglomeration and dispersion of the information and communications industry, we quantify the spatial agglomeration of the information and communications industry in Japan’s major cities. Using the town and district data from the Economic Census for Economic Activity, we attempted a spatial analysis of the information and communications industry in the Tokyo Special Wards as well as in Sapporo, Sendai, Hiroshima, and Fukuoka, which have regional central functions. As a result of detecting spatial autocorrelation in small areas within each city, hotspots indicating the agglomeration of information and communications industry offi ces were found in the city center of each city. At the same time, we were able to confi rm the impact of agglomeration economies, which are the premise of the self-organizing model, and confi rmed that the information and communications industry is an industry suitable for simulation of the self-organizing model.
Krugman(1996)was the fi rst to model the self-organizing model in cities and clarifi ed the emergence principle of peripheral cities, but this was limited to numerical simulations. Later, Kumar et al.(2007)used actual data to show that Krugman’s self-organizing model could be applied to predict corporate agglomeration and dispersion. In this paper, we use an agent-based model to examine whether a self-organizing model is also effective in reproducing and predicting the concentration and dispersion of the information and communications industry in Japanese cities.

kn-title=Effects of dapagliflozin on myoglobin efflux from cardiomyocyte during myocardial ischemia/reperfusion in anesthetized rats
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=It has been suggested that sodium-glucose cotransporter 2 (SGLT2) inhibitors have cardioprotective effects during myocardial ischemia/reperfusion (I/R) independent of glucose-lowering action. However, the effects of SGLT2 inhibitors on structural damage to cardiomyocytes in the ischemic region during I/R remain unknown. We applied a microdialysis technique to the heart of anesthetized rats and investigated the effects of an SGLT2 inhibitor, dapagliflozin, on myocardial interstitial myoglobin levels in the ischemic region during coronary occlusion followed by reperfusion. Dapagliflozin was administered systemically (40 mu g/body iv) or locally via a dialysis probe (100 mu M and 1 mM) 30 min before coronary occlusion. In the vehicle group, coronary occlusion increased the dialysate myoglobin concentration in the ischemic region. Reperfusion further increased the dialysate myoglobin concentration. Intravenous administration of dapagliflozin reduced dialysate myoglobin concentration during ischemia and at 0-15 min after reperfusion, but local administration (100 mu M and 1 mM) did not. Therefore, acute systemic administration of dapagliflozin prior to ischemia has cardioprotective effects on structural damage during I/R.

kn-title=Effect of Radon Inhalation on Murine Brain Proteins: Investigation Using Proteomic and Multivariate Analyses
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required. Although several studies have used proteomics to investigate the effects of radon inhalation on body proteins, none has focused on brain proteins. In this study, we evaluated the expression status of proteins in murine brains using proteomic and multivariate analyses to identify those whose expressions changed following two days of radon inhalation at a concentration of 1,500 Bq/m3. We found associations of radon inhalation with the expressions of seven proteins related to neurotransmission and heat shock. These proteins may be proposed as biomarkers indicative of radon inhalation. Although further studies are required to obtain the detailed biological significance of these protein alterations, this study contributes to the elucidation of the biological effects of radon
inhalation as a low-dose radiation.

kn-title=Phenotypic and Genetic Characteristics of Carbapenemase-Producing Enterobacterales Isolates at Okayama University Hospital
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Spread of carbapenemase-producing Enterobacterales (CPE) is an ongoing public health issue worldwide, including in Japan. In this study, we investigated the phenotypic and genetic characteristics of CPE isolates at Okayama University Hospital over the 5 years (2013-2018) prior to the outbreak of the 2019 coronavirus pandemic. Of 24 carbapenem-resistant Enterobacterales isolated during the study period, we identified 8 CPE isolates harboring blaIMP-1 (5 isolates) and blaIMP-6 genes (3 isolates). Bacterial species and carbapenem susceptibility patterns exhibited diversity. Minimum inhibitory concentrations (MICs) of meropenem were generally higher than those of imipenem and biapenem. Results of pulsed-field gel electrophoresis demonstrated that neither clonal nor plasmid-mediated outbreaks of blaIMP-harboring CPE isolates have developed at our hospital. One Klebsiella oxytoca isolate showed a high MIC (128 μg/mL) of meropenem, which could be explained by the high plasmid copy number. Subsequent analysis of this isolate may elucidate the intricacies of carbapenem resistance profiles among CPE isolates. Collectively, our findings underscore the necessity for ongoing genetic surveillance of CPE, complemented by tailored approaches for infection prevention and control.

kn-abstract=Oral bacteria cause tooth caries and periodontal disease. Much research is being conducted to prevent both major oral diseases by rendering dental materials' antimicrobial potential. However, such antimicrobial materials are regarded as 'combination' products and face high hurdles for regulatory approval. We loaded inorganic montmorillonite with the antimicrobial agent cetylpyridinium chloride, referred to below as 'CPC-Mont'. CPC-Mont particles in a 1, 3 and 5 wt% concentration were added to the considered gold-standard self-etch adhesive Clearfil SE Bond 2 ('CSE2'; Kuraray Noritake) to render its antibacterial potential (CSE2 without CPC-Mont served as control). Besides measuring (immediate) bonding effectiveness and (aged) bond durability to dentin, the antibacterial activity against S. mutans and the polymerization-conversion rate was assessed. Immediate and aged bond strength was not affected by 1 and 3 wt% CPC-Mont addition, while 5 wt% CPC-Mont significantly lowered bond strength and bond durability. The higher the concentration of the antimicrobial material added, the stronger the antimicrobial activity. Polymerization conversion was not affected by the CPC-Mont addition in any of the three concentrations. Hence, adding 3 wt% CPC-Mont to the two-step self-etch adhesive rendered additional antimicrobial potential on top of its primary bonding function.

kn-title=Surface Pre-Reacted Glass-Ionomer Eluate Suppresses Osteoclastogenesis through Downregulation of the MAPK Signaling Pathway
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Surface pre-reacted glass-ionomer (S-PRG) is a new bioactive filler utilized for the restoration of decayed teeth by its ability to release six bioactive ions that prevent the adhesion of dental plaque to the tooth surface. Since ionic liquids are reported to facilitate transepithelial penetration, we reasoned that S-PRG applied to root caries could impact the osteoclasts (OCs) in the proximal alveolar bone. Therefore, this study aimed to investigate the effect of S-PRG eluate solution on RANKL-induced OC-genesis and mineral dissolution in vitro. Using RAW264.7 cells as OC precursor cells (OPCs), TRAP staining and pit formation assays were conducted to monitor OC-genesis and mineral dissolution, respectively, while OC-genesis-associated gene expression was measured using quantitative real-time PCR (qPCR). Expression of NFATc1, a master regulator of OC differentiation, and the phosphorylation of MAPK signaling molecules were measured using Western blotting. S-PRG eluate dilutions at 1/200 and 1/400 showed no cytotoxicity to RAW264.7 cells but did significantly suppress both OC-genesis and mineral dissolution. The same concentrations of S-PRG eluate downregulated the RANKL-mediated induction of OCSTAMP and CATK mRNAs, as well as the expression of NFATc1 protein and the phosphorylation of ERK, JNK, and p38. These results demonstrate that S-PRG eluate can downregulate RANKL-induced OC-genesis and mineral dissolution, suggesting that its application to root caries might prevent alveolar bone resorption.

kn-title=Revisiting the hormonal control of sexual dimorphism in chicken feathers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Sexual dimorphism in plumage is widespread among avian species. In chickens, adult females exhibit countershading, characterized by dull-colored round feathers lacking fringe on the saddle, while adult males display vibrant plumage with deeply fringed bright feathers. This dimorphism is estrogen-dependent, and administering estrogen to males transforms their showy plumage into cryptic female-like plumage. Extensive studies have shown that estrogen’s role in female plumage formation requires thyroid hormone; however, the precise mechanisms of their interaction remain unclear. In this study, we investigated the roles of estrogen and thyroid hormone in creating sexual dimorphism in the structure and coloration of saddle feathers by administering each hormone to adult males and observing the resulting changes in regenerated feathers induced by plucking. RT-PCR analysis revealed that the expression of type 3 deiodinase (DIO3), responsible for thyroid hormone inactivation, correlates with fringing. Estrogen suppressed DIO3 and agouti signaling protein (ASIP) expression while stimulating BlSK1, a marker of barbule cells, resulting in female-like feathers with mottled patterns and lacking fringes. Administration of thyroxine (T4) stimulated BlSK1 and proopiomelanocortin (POMC) expression, with no effect on ASIP, leading to the formation of solid black feathers lacking fringes. Triiodothyronine (T3) significantly increased POMC expression in pulp cells in culture. Taken together, these findings suggest that estrogen promotes the formation of solid vanes by suppressing DIO3 expression, while also inducing the formation of mottled patterns through inhibition of ASIP expression and indirect stimulation of melanocortin expression via changes in local T3 concentration. This is the first report describing molecular mechanism underlying hormonal crosstalk in creating sexual dimorphism in feathers.

kn-title=The neurotoxicity of psychoactive phenethylamines “2C series” in cultured monoaminergic neuronal cell lines
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose The aim of this study was to evaluate the neurotoxicity of psychoactive abused 2,5-dimethoxy-substituted phenethylamines “2C series” in monoaminergic neurons.
Methods After the exposure to “2C series”, 2,5-dimethoxy-4-propylthiophenethylamine (2C-T-7), 2,5-dimethoxy-4-isopropylthiophenethylamine (2C-T-4), 2,5-dimethoxy-4-ethylthiophenthylamine (2C-T-2), 2,5-dimethoxy-4-iodophenethylamine (2C-I) or 2,5-dimethoxy-4-chlorophenethylamine (2C-C), we examined their neurotoxicity, morphological changes, and effects of concomitant exposure to 3,4-methylenedioxymethamphetamine (MDMA) or methamphetamine (METH), using cultured neuronal dopaminergic CATH.a cells and serotonin-containing B65 cells.
Results Single dose exposure to “2C series” for 24 h showed significant cytotoxicity as increase in lactate dehydrogenase (LDH) release from both monoaminergic neurons: 2C-T-7, 2C-C (EC50; 100 µM) > 2C-T-2 (150 µM), 2C-T-4 (200 µM) > 2C-I (250 µM) in CATH.a cells and 2C-T-7, 2C-I (150 µM) > 2C-T-2 (250 µM) > 2C-C, 2C-T-4 (300 µM) in B65 cells. The “2C series”-induced neurotoxicity in both cells was higher than that of MDMA or METH (EC50: ≥ 1–2 mM). In addition, apoptotic morphological changes were observed at relatively lower concentrations of “2C series”. The concomitant exposure to non-toxic dose of MDMA or METH synergistically enhanced 2C series drugs-induced LDH release and apoptotic changes in B65 cells, but to a lesser extent in CATH.a cells. In addition, the lower dose of 2C-T-7, 2C-T-2 or 2C-I promoted reactive oxygen species production in the mitochondria of B65 cells, even at the early stages (3 h) without apparent morphological changes.
Conclusion The 2,5-dimethoxy-substitution of “2C series” induced severe neurotoxicity in both dopaminergic and serotonin-containing neurons. The non-toxic dose of MDMA or METH synergistically enhanced its neurotoxicity in serotonergic neurons.

kn-title=Reduction with zinc - Impact on the determination of nitrite and nitrate ions using microfluidic paper-based analytical devices
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We used a microfluidic paper-based analytical device (mu PAD) to investigate the influence that zinc reduction exerts on the determination of nitrite and nitrate ions in natural water samples. The mu PAD consists of layered channels for the reduction of nitrate to nitrite with zinc powder and the subsequent detection of nitrite with Griess reagent. The amount of zinc, number of layers, and reaction time for the reduction were optimized to obtain an intense signal for nitrate. Initially, the sensitivity to nitrate corresponded to 55% that of nitrite, which implied an incomplete reduction. We found, however, that zinc decreased the sensitivity to nitrite in both the mu PAD and spectrophotometry. The sensitivity to nitrite was decreased by 48% in spectrophotometry and 68% in the mu PAD following the reaction with zinc. One of the reasons for the decreased sensitivity is attributed to the production of ammonia, as we elucidated that both nitrite and nitrate produced ammonia via the reaction with zinc. The results suggest that the total concentration of nitrite and nitrate must be corrected by constructing a calibration curve for nitrite with zinc, in addition to developing curves for nitrate with zinc and for nitrite without zinc. Using these calibration curves, the absorbance at different concentration ratios of nitrite and nitrate ions could be reproduced via calculation using the calibration curves with zinc for nitrite and nitrate. Eventually, the developed mu PAD was applied to the determination of nitrite and nitrate ions in natural water samples, and the results were compared with those using a conventional spectrophotometric method. The results of the mu PAD are in good agreement with those of conventional spectrophotometry, which suggests that the mu PAD is reliable for the measurement of nitrite and nitrate ions in natural water samples.

kn-title=Cytosolic acidification and oxidation are the toxic mechanisms of SO2 in Arabidopsis guard cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=SO2/H2SO3 can damage plants. However, its toxic mechanism has still been controversial. Two models have been proposed, cytosolic acidification model and cellular oxidation model. Here, we assessed the toxic mechanism of H2SO3 in three cell types of Arabidopsis thaliana, mesophyll cells, guard cells (GCs), and petal cells. The sensitivity of GCs of Chloride channel a (CLCa)-knockout mutants to H2SO3 was significantly lower than those of wildtype plants. Expression of other CLC genes in mesophyll cells and petal cells were different from GCs. Treatment with antioxidant, disodium 4,5-dihydroxy-1,3-benzenedisulfonate (tiron), increased the median lethal concentration (LC50) of H2SO3 in GCs indicating the involvement of cellular oxidation, while the effect was negligible in mesophyll cells and petal cells. These results indicate that there are two toxic mechanisms of SO2 to Arabidopsis cells: cytosolic acidification and cellular oxidation, and the toxic mechanism may vary among cell types.

kn-title=Impact of Serum Indoxyl Sulfate on One-Year Adverse Events in Chronic Kidney Disease Patients with Heart Failure
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background/Objectives: Indoxyl sulfate, a uremic toxin, is associated with mortality and cardiovascular events in patients with chronic kidney disease (CKD). This study aimed to evaluate the prognostic implications of serum indoxyl sulfate levels in patients with heart failure and CKD. Methods and Results: This was a prospective multicenter observational study. Overall, 300 patients with chronic heart failure with a previous history of hospitalization and an estimated glomerular filtration rate (eGFR) of 45 mL/min/1.73 m2 or less (CKD stage G3b to G5) without dialysis were analyzed. The primary outcome assessed in a time-to-event analysis from the measurement of indoxyl sulfate was a composite of all-cause death, hospitalization for heart failure, nonfatal myocardial infarction, and nonfatal stroke. Clinical events were followed-up to one year after indoxyl sulfate measurement. The median patient age was 75 years, and 57% of the patients were men. We divided the cohort into low and high indoxyl sulfate categories according to a median value of 9.63 mg/mL. The primary outcome occurred in 27 of 150 patients (18.0%) in the low indoxyl sulfate group and 27 of 150 patients (18.0%) in the high indoxyl sulfate group (hazard ratio, 1.00; 95% confidence interval, 0.58 to 1.70, p = 0.99). In the post hoc exploratory analyses, the results were consistent across age, sex, body mass index, left ventricular ejection fraction, eGFR, and N-terminal pro b-type natriuretic peptide. Conclusions: Among heart failure patients with CKD stages G3b to 5G, serum indoxyl sulfate concentrations were not significantly associated with the subsequent occurrence of cardiovascular events.

kn-title=New Delhi Metallo-Beta-Lactamase Inhibitors: A Systematic Scoping Review
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background/Objectives: Among various carbapenemases, New Delhi metallo-beta-lactamases (NDMs) are recognized as the most powerful type capable of hydrolyzing all beta-lactam antibiotics, often conferring multi-drug resistance to the microorganism. The objective of this review is to synthesize current scientific data on NDM inhibitors to facilitate the development of future therapeutics for challenging-to-treat pathogens. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews, we conducted a MEDLINE search for articles with relevant keywords from the beginning of 2009 to December 2022. We employed various generic terms to encompass all the literature ever published on potential NDM inhibitors. Results: Out of the 1760 articles identified through the database search, 91 met the eligibility criteria and were included in our analysis. The fractional inhibitory concentration index was assessed using the checkerboard assay for 47 compounds in 37 articles, which included 8 compounds already approved by the Food and Drug Administration (FDA) of the United States. Time-killing curve assays (14 studies, 25%), kinetic assays (15 studies, 40.5%), molecular investigations (25 studies, 67.6%), in vivo studies (14 studies, 37.8%), and toxicity assays (13 studies, 35.1%) were also conducted to strengthen the laboratory-level evidence of the potential inhibitors. None of them appeared to have been applied to human infections. Conclusions: Ongoing research efforts have identified several potential NDM inhibitors; however, there are currently no clinically applicable drugs. To address this, we must foster interdisciplinary and multifaceted collaborations by broadening our own horizons.

en-abstract=
kn-abstract=Perovskite based on cesium bismuth bromide offers a compelling, non-toxic alternative to lead-containing counterparts in optoelectronic applications. However, its widespread usage is hindered by its wide bandgap. This study investigates a significant bandgap tunability achieved by introducing Fe doping into the inorganic, lead-free, non-toxic, and stable Cs3Bi2Br9 perovskite at varying concentrations. The materials were synthesized using a facile method, with the aim of tuning the optoelectronic properties of the perovskite materials. Characterization through techniques such as X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, energy dispersive spectroscopy (EDS), and UV-vis spectroscopy was conducted to elucidate the transformation mechanism of the doping materials. The substitution process results in a significant change in the bandgap energy, transforming from the pristine Cs3Bi2Br9 with a bandgap of 2.54 eV to 1.78 eV upon 70% Fe doping. The addition of 50% Fe in Cs3Bi2Br9 leads to the formation of the orthorhombic structure in Cs2(Bi,Fe)Br5 perovskite, while complete Fe alloying at 100% results in the phase formation of CsFeBr4 perovskite. Our findings on regulation of bandgap energy and crystal structure through B site substitution hold significant promise for applications in optoelectronics.

kn-title=A Novel Peptidome Technology for the Diagnosis of Mild Cognitive Impairment and Alzheimer’s Disease by Selected Reaction Monitoring
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background:With the aging of populations worldwide, Alzheimer’s disease (AD) has become a concern due to its high prevalence and the continued lack of established treatments. Early diagnosis is required as a preventive intervention to modify the disease’s progression. In our previous study, we performed peptidomic analysis of serum samples obtained from AD patients and age-matched healthy subjects to seek peptide biomarker candidates for AD by using BLOTCHIP-MS analysis, and identified four peptides as AD biomarker candidates.
Objective:The objective was to validate the serum biomarker peptides to distinguish mild cognitive impairment (MCI) and AD in comparison to cognitively healthy controls using a new peptidome technology, the Dementia Risk Test.
Methods:We enrolled 195 subjects with normal cognitive function (NC; n = 70), MCI (n = 55), and AD (n = 70), The concentrations of cognitive impairment marker peptides (Fibrinogen α chain (FAC), Fibrinogen β chain (FBC), Plasma protease C1 inhibitor (PPC1I), α2-HS-glycoprotein (AHSG)) were quantified by using a selected reaction monitoring assay based on liquid chromatography-MS/MS.
Results:The present study confirmed that three peptides, FAC, FBC, and PPC1I, were significantly upregulated during the onset of AD. This three-peptide set was both highly sensitive in determining AD (sensitivity: 85.7%, specificity: 95.7%, AUC: 0.900) and useful in distinguishing MCI (sensitivity: 61.8%, specificity: 98.6%, AUC: 0.824) from NC.
Conclusions:In this validation study, we confirmed the high diagnostic potential of the three peptides identified in our previous study as candidate serum biomarkers for AD. The Dementia Risk Test may be a powerful tool for detecting AD-related pathological changes.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=High-performance and small-sized heat exchangers have been demanded due to the miniaturization and higher output of electronic devices, lasers, and energy harvesting/storage systems. Graphene nanosheet suspension has attracted attention as a next-generation nanofluid because of its high thermal conductivity and low pressure drop, while being dispersed stably without any additives. Graphene-based nanofluids have been mostly investigated using graphene oxide, and there are a few studies on pure graphene because of the limitation in mass production and stabilization at high concentrations of graphene. In this study, we prepared a 10 wt. % high-concentration few-layer graphene suspension by pulverizing graphite particles. Scanning electron microscopy, atomic force microscopy, and Raman spectra confirmed the few-layer graphene is formed in the suspension. The thermal conductivity of the suspension increased with concentration and suddenly jumped at a specific concentration. Furthermore, a significant improvement in thermal conductivity of >40% compared to base liquid was confirmed at 10 wt. % graphene content. A similar trend was observed for electrical resistance; 10 wt. % graphene suspension showed 62% lower resistance than that of 1 wt. %. These results suggest the percolation of graphene in a liquid, which has not been observed for graphene-based materials in previous research.

kn-title=Effect of artificial defect on tensile properties of thin titanium alloy wire
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study investigated the effects of artificial defects, introduced via focused ion beam (FIB) processing, on the tensile properties of thin titanium alloy wires (Ti-6Al-4V). Results indicated that the defective wires fractured when the net-section nominal stress reached the ultimate tensile strength of the smooth wires, probably because of localized stress concentrations relaxing due to plastic deformation around the defects. The effect of defects on tensile properties was classified into three regions based on the size of the defect area. In the case of small defects, wires fractured at the smooth area away from the defects where the cross-sectional strength was lower. In this case, the defects minimally affected the tensile properties. This is attributable to variations in the cross-sectional strength of the wire, which resulted in some sections with lower strength as compared with the defect area. In the case of medium-sized defects, the fracture strain decreased gradually as the defect area increased. Finally, in the case of large defects, the fracture strain was extremely small. The boundary between the medium-sized and large defects indicates the transition from plastic deformation to no plastic deformation in the smooth area.

kn-title=Unabsorbed Fecal Fat Content Correlates with a Reduction of Immunoglobulin a Coating of Gut Bacteria in High‐Lard Diet‐Fed Mice
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Scope: Immunoglobulin A (IgA) selectively coats gut bacteria and contributes to regulatory functions in gastrointestinal inflammation and glucose metabolism. Excess intake of lard leads to decrease in the IgA coating of gut bacteria, although the underlying mechanisms remain unknown. This study validates how unabsorbed fat derived from a high-lard diet in the gut affects the IgA coating of bacteria, as assessed in mouse models using three types of dietary fat (lard, medium-, and long-chain triglycerides [MLCTs], and medium-chain triglycerides [MCTs]) exhibiting different digestibilities.
Methods and results: C57BL/6J mice are maintained on diets containing lard, MLCTs, or MCTs at 7% or 30% w/w for 10 weeks (n = 6 per group). The fecal fatty acid concentration is measured to quantify unabsorbed fat content. The ratio of IgA-coated bacteria to total bacteria (IgA coating ratio) in the feces is measured by flow cytometry. Compared to lard-fed mice, MLCT- and MCT-fed mice exhibit lower fecal concentrations of palmitic acid, stearic acid, and oleic acid and higher IgA coating ratios at both 7% and 30% dietary fat, and these parameters exhibit significant negative correlations.
Conclusion: Unabsorbed fat content in the gut may result in attenuated IgA coating of bacteria in high-lard diet-fed mice.

kn-title=Prognostic Implications of Insulin Resistance in Heart Failure in Japan
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Diabetes mellitus (DM) is a major risk and prognostic factor for heart failure (HF). Insulin resistance (IR) is an important component of DM, but the relationship between IR and HF prognosis has not yet been established across a wide variety of HF populations. We retrospectively evaluated the relationship between IR and clinical outcomes of HF patients at our hospital between 2017 and 2021. IR was defined as a homeostatic model assessment of IR (HOMA-IR) index >= 2.5, calculated from fasting blood glucose and insulin concentrations. The primary outcome was a composite of all-cause death and hospitalisation for HF (HHF). Among 682 patients included in the analyses, 337 (49.4%) had IR. The median age was 70 [interquartile range (IQR): 59-77] years old, and 66% of the patients were men. Among the patients, 41% had a left ventricular ejection fraction below 40%, and 32% had DM. The median follow-up period was 16.5 [IQR: 4.4-37.3] months. IR was independently associated with the primary outcome (HR: 1.91, 95% CI: 1.39-2.62, p < 0.0001), death (hazard ratio [HR]: 1.86, 95% confidence interval [CI]: 1.28-2.83, p < 0.01), and HHF (HR: 1.91, 95% CI: 1.28-2.83, p < 0.01). HOMA-IR is an independent prognostic factor of HF in a wide variety of HF populations.

kn-title=Freeze-thaw Resistance of Concrete using Ground Granulated Blast-furnace Slag and Blast-furnace Slag Sand in Salt Water
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The freeze-thaw resistance of concrete is significantly lower in salt water than in fresh water. Concrete deteriorates through repeated freezing and thawing, but in salt water, freezing alone leads to destruction. This paper investigated the effect of calcium hydroxide in concrete on the failure of concrete under such low temperatures. Calcium hydroxide precipitates at the transition zone between aggregate and cement paste due to the hydration of cement. The lower the temperature and the higher the concentration of salt water, the more calcium hydroxide dissolves. From concrete, more calcium hydroxide is eluted in salt water than in fresh water. This accelerates the deterioration of mortar and concrete due to freeze-thaw action. Mortar and concrete using ground granulated blast-furnace slag produces less calcium hydroxide. In mortar and concrete using blast-furnace slag sand, calcium hydroxide precipitated around the aggregate reacts with cement paste and blast-furnace slag sand to modify the transition zone. From these results, it was clarified that concrete using blast-furnace slag exhibits high freeze-thaw resistance even in salt water.

kn-title=Volume X-Ray Micro-Computed Tomography Analysis of the Early Cephalized Central Nervous System in a Marine Flatworm, Stylochoplana pusilla
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Platyhelminthes are a phylum of simple bilaterian invertebrates with prototypic body systems. Compared with non-bilaterians such as cnidarians, the bilaterians are likely to exhibit integrated free-moving behaviors, which require a concentrated nervous system “brain” rather than the distributed nervous system of radiatans. Marine flatworms have an early cephalized ‘central’ nervous system compared not only with non-bilaterians but also with parasitic flatworms or freshwater planarians. In this study, we used the marine flatworm Stylochoplana pusilla as an excellent model organism in Platyhelminthes because of the early cephalized central nervous system. Here, we investigated the three-dimensional structures of the flatworm central nervous system by the use of X-ray micro-computed tomography (micro-CT) in a synchrotron radiation facility. We found that the obtained tomographic images were sufficient to discriminate some characteristic structures of the nervous system, including nerve cords around the cephalic ganglion, mushroom body-like structures, and putative optic nerves forming an optic commissure-like structure. Through the micro-CT imaging, we could obtain undistorted serial section images, permitting us to visualize precise spatial relationships of neuronal subpopulations and nerve tracts. 3-D micro-CT is very effective in the volume analysis of the nervous system at the cellular level; the methodology is straightforward and could be applied to many other non-model organisms.

kn-title=Circadian Rhythms Fluctuate the Treatment Effects of Intravesical Treatments on Rat Urinary Frequency Models
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Objectives. It is still not clear how the intravesical instillation of drugs affects rat urinary frequency. This study aimed to examine the dynamics of intravesical treatments' treatment effect on rat urinary frequency models by real-time and extended monitoring using a novel continuous urination monitoring system. Methods. Nine eleven-week-old female Wistar rats were divided into three groups to receive intravesical instillation of 0.1% acetic acid (AA), 1.0% AA, or phosphate-buffered saline (PBS). Thirty minutes later, these drugs were voided, and rats were moved to a continuous urination monitoring system, UM-100. UM-100 monitored rat urination quantitatively and continuously for 24 hours. Rats were then euthanized, and histopathologic examinations using a damage score validated the severity of bladder inflammation. We used nine additional rats to determine the treatment effect of various drugs against the urinary frequency. These rats were also treated with 1.0% AA in the same way and divided into three groups (n = 3 each) to receive intravesical instillation of lidocaine, silver nitrate (AgNO3), or dimethyl sulfoxide (DMSO), respectively. Thirty minutes later, rats were catheterized again and moved to the UM-100, and their voiding was monitored for 24 hours. Results. Intravesical instillation of AA increased the urinary frequency and decreased the mean voided volume (VV) in a concentration-dependent manner, with statistical significance at a concentration of 1.0% (urinary frequency; p = 0.0007 , mean VV; p = 0.0032 , respectively) compared with PBS. Histopathological analysis of these models demonstrated a significantly higher damage score of bladder mucosa in both 0.1% AA and 1.0% AA compared with PBS, with the severity in concordance with the clinical severity of urinary frequency (0.1% AA: p < 0.0001 , 1.0% AA: p < 0.0001 ). Moreover, intravesical instillation of lidocaine, AgNO3, and DMSO decreased the urinary frequency. Continuous monitoring with UM-100 also demonstrated that the treatment effect of these intravesically instilled drugs occurred only at night. Conclusions. The extended monitoring of rat urination by UM-100 revealed a significant fluctuation in the treatment effect of intravesically instilled drugs between day and night. These findings may help establish novel therapies for urinary frequency.

kn-abstract=The aim of this study is to investigate the relationship of the lipid profile, dysfunctional high-density lipoprotein, ischaemia-modified albumin and thiol–disulfide homeostasis with cognitive impairment, fatigue and sleep disorders in patients with multiple sclerosis. The cognitive functions of patients were evaluated with the Brief International Cognitive Assessment for Multiple Sclerosis battery. Fatigue was evaluated with the Fatigue Severity Scale and the Fatigue Impact Scale. The Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale were used to assess patients’ sleep disturbance. Peripheral blood samples were collected, and lipid levels and myeloperoxidase and paraoxonase activity were measured. The myeloperoxidase/paraoxonase ratio, which indicates dysfunctional high-density lipoprotein, was calculated. Thiol–disulfide homeostasis and ischaemia-modified albumin were measured.
We did not identify any relationship between dysfunctional high-density lipoprotein and the physical disability, cognitive decline, fatigue and sleep problems of multiple sclerosis. Thiol–disulfide homeostasis was associated with cognitive scores. The shift of the balance towards disulfide was accompanied by a decrease in cognitive scores. On the other hand, we did not detect any relationship between fatigue and sleep disorders and thiol–disulfide homeostasis. Our findings revealed a possible correlation between cognitive dysfunction and thiol–disulfide homeostasis in multiple sclerosis patients.

kn-title=Effect of Antimicrobial Photodynamic Therapy on the Tongue Dorsum on Reducing Halitosis and the Duration of the Effect: A Randomized Clinical Trial
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Antimicrobial photodynamic therapy (PDT) is a treatment that is gaining popularity in modern clinical medicine. However, little is known about the effect of PDT alone on reducing oral halitosis and the duration of the effect. This trial examined the effect of PDT on the tongue dorsum on reducing oral halitosis and the duration of the effect. This study was approved by the Ethics Committee of Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, and Okayama University Hospital (CRB20-015), and it was registered in the Japan Registry of Clinical Trials (jRCTs061200060). Twenty-two participants were randomly assigned to two groups: an intervention group and control group. PDT was performed in the intervention group using red laser emission and methylene blue gel on the middle and posterior area of the tongue dorsum. The concentration of volatile sulfur compounds, bacterial count on the tongue dorsum, probing pocket depth, bleeding on probing, and simplified oral debris index score were determined before and 1 week after PDT. The Mann-Whitney U test was used to assess the significance of the differences in each parameter between the two groups. We found that the hydrogen sulfide concentration and bacterial count on the tongue dorsum were decreased in the intervention group, but there was no statistically significant difference between the two groups. These results indicated that performing only PDT on the tongue dorsum may not contribute to reducing halitosis.

kn-title=Enhancing effect of the coexisting alpha-tocopherol on quercetin absorption and metabolism
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of this study is to investigate the modulating effect of coexisting food components on the absorption and metabolism of quercetin and blood plasma antioxidant potentials. The combination of quercetin with α-tocopherol (αT), cellulose, or a commercially available vegetable beverage containing αT and dietary fiber was orally administered to mice. Compared to the single administration of quercetin aglycone, the coadministration of αT with quercetin significantly increased the plasma quercetin concentration at 0.5 h, whereas the combination of quercetin and cellulose decreased it. Interestingly, the administration of quercetin mixed with the vegetable beverage showed no significant change in the quercetin concentration in the mice plasma. The treatment of the cells with the blood plasma after the coadministration of αT with quercetin significantly upregulated the gene expression of the antioxidant enzyme (heme oxygenase-1), whereas the quercetin and cellulose combination did not. In the plasma of the quercetin-administered mice, eight types of quercetin metabolites were detected, and their quantities were affected by the combination with αT. The potentials of the heme oxygenase-1 gene expression by these metabolites were very limited, although several metabolites showed radical scavenging activities comparable to aglycone in the in vitro assays. These results suggested that the combination of αT potentiates the quercetin absorption and metabolism and thus the plasma antioxidant potentials, at least in part, by the quantitative changes in the quercetin metabolites.

kn-title=Li-Ion Transport and Solution Structure in Sulfolane-Based Localized High-Concentration Electrolytes
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Localized high-concentration electrolytes (LHCEs), which are mixtures of highly concentrated electrolytes (HCEs) and non-coordinating diluents, have attracted significant interest as promising liquid electrolytes for next-generation Li secondary batteries, owing to their various beneficial properties both in the bulk and at the electrode/electrolyte interface. We previously reported that the large Li+-ion transference number in sulfolane (SL)-based HCEs, attributed to the unique exchange/hopping-like Li+-ion conduction, decreased upon dilution with the non-coordinating hydrofluoroether (HFE) despite the retention of the local Li+-ion coordination structure. Therefore, in this study, we investigated the effects of HFE dilution on the Li+ transference number and the solution structure of SL-based LHCEs via the analysis of dynamic ion correlations and molecular dynamics simulations. The addition of HFE caused nano-segregation in the SL-based LHCEs to afford polar and nonpolar domains and fragmentation of the polar ion-conducting pathway into smaller clusters with increasing HFE content. Analysis of the dynamic ion correlations revealed that the anti-correlated Li+–Li+ motions were more pronounced upon HFE addition, suggesting that the Li+ exchange/hopping conduction is obstructed by the non-ion-conducting HFE-rich domains. Thus, the HFE addition affects the entire solution structure and ion transport without significantly affecting the local Li+-ion coordination structure. Further studies on ion transport in LHCEs would help obtain a design principle for liquid electrolytes with high ionic conductivity and large Li+-ion transference numbers.

kn-title=Molecular mechanism of the common and opposing cosolvent effects of fluorinated alcohol and urea on a coiled coil protein
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Alcohols and urea are widely used as effective protein denaturants. Among monohydric alcohols, 2,2,2-trifluoroethanol (TFE) has large cosolvent effects as a helix stabilizer in proteins. In contrast, urea efficiently denatures ordered native structures, including helices, into coils. These opposing cosolvent effects of TFE and urea are well known, even though both preferentially bind to proteins; however, the underlying molecular mechanism remains controversial. Cosolvent-dependent relative stability between native and denatured states is rigorously related to the difference in preferential binding parameters (PBPs) between these states. In this study, GCN4-p1 with two-stranded coiled coil helices was employed as a model protein, and molecular dynamics simulations for the helix dimer and isolated coil were conducted in aqueous solutions with 2 M TFE and urea. As 2 M cosolvent aqueous solutions did not exhibit clustering of cosolvent molecules, we were able to directly investigate the molecular origin of the excess PBP without considering the enhancement effect of PBPs arising from the concentration fluctuations. The calculated excess PBPs of TFE for the helices and those of urea for the coils were consistent with experimentally observed stabilization of helix by TFE and that of coil by urea. The former was caused by electrostatic interactions between TFE and side chains of the helices, while the latter was attributed to both electrostatic and dispersion interactions between urea and the main chains. Unexpectedly, reverse-micelle-like orientations of TFE molecules strengthened the electrostatic interactions between TFE and the side chains, resulting in strengthening of TFE solvation.

kn-title=Endoscopic manifestation of intestinal transplant-associated microangiopathy after stem cell transplantation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Endoscopic features of intestinal transplant-associated microangiopathy (iTAM) have not been comprehensively investigated. This study aimed to examine the endoscopic characteristics of patients diagnosed with iTAM.
Methods This retrospective analysis included 14 patients pathologically diagnosed with iTAM after stem cell transplantation for hematolymphoid neoplasms (n = 13) or thalassemia (n = 1). The sex, age at diagnosis, endoscopic features, and prognosis of each patient were assessed. Serological markers for diagnosing transplant-associated thrombotic microangiopathy were also evaluated.
Results The mean age at the time of iTAM diagnosis was 40.2 years. Patients diagnosed based on the pathognomonic pathological changes of iTAM presented with diverse symptoms at the times of endoscopic examinations, including diarrhea (n = 10), abdominal pain (n = 5), nausea (n = 4), appetite loss (n = 2), bloody stools (n = 2), abdominal discomfort (n = 1), and vomiting (n = 1). At the final follow-up, six patients survived, while eight patients succumbed, with a median time of 100.5 days (range: 52-247) post-diagnosis. Endoscopic manifestations included erythematous mucosa (n = 14), erosions (n = 13), ulcers (n = 9), mucosal edema (n = 9), granular mucosa (n = 9), and villous atrophy (n = 4). Erosions and/or ulcers were primarily observed in the colon (10/14, 71%), followed by the ileum (9/13, 69%), stomach (4/10, 40%), cecum (5/14, 36%), duodenum (3/10, 30%), rectum (4/14, 29%), and esophagus (1/10, 10%). Cytomegalovirus infection (n = 4) and graft-versus-host disease (n = 2) coexisted within the gastrointestinal tract. Patients had de novo prolonged or progressive thrombocytopenia (6/14, 43%), decreased hemoglobin concentration (4/14, 29%), reduced serum haptoglobin level (3/14, 21%), and a sudden and persistent increase in lactate dehydrogenase level (2/14, 14%). Peripheral blood samples from 12 patients were evaluated for schistocytes, with none exceeding 4%.
Conclusions This study provides a comprehensive exploration of the endoscopic characteristics of iTAM. Notably, all patients exhibited erythematous mucosa throughout the gastrointestinal tract, accompanied by prevalent manifestations, such as erosions (93%), ulcers (64%), mucosal edema (64%), granular mucosa (64%), and villous atrophy (29%). Because of the low positivity for serological markers of transplant-associated thrombotic microangiopathy in patients with iTAM, endoscopic evaluation and biopsy of these lesions are crucial, even in the absence of these serological features.

kn-title=Photon-Counting Detector CT: Potential for 75% Reduction in Contrast Medium Amount: A Phantom Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study aimed to evaluate the potential reduction in contrast medium utilization using photon-counting detector computed tomography (PCD-CT). One PCD-CT scan (CT1) and three conventional (non-PCD-CT) CT scans (CT2-CT4) were performed using a multi-energy CT phantom that contained eight rods with different iodine concentrations (0.2, 0.5, 1, 2, 5, 10, 15, and 20 mg/ml). The CT values of the seven groups (CT1 for 40, 50, 60, and 70 keV; and CT2-4) were measured. Noise and contrast-to-noise ratio (CNR) were assessed for the eight rods at various iodine concentrations. CT2 and CT1 (40 keV) respectively required 20 mg/ml and 5 mg/ml of iodine, indicating that a comparable contrast effect could be obtained with approximately one-fourth of the contrast medium amount. The standard deviation values increased at lower energy levels irrespective of the iodine concentration. The CNR exhibited a decreasing trend with lower iodine concentrations, while it remained relatively stable across all iodine levels (40-70 keV). This study demonstrated that virtual monochromatic 40 keV images offer a similar contrast effect with a reduced contrast medium amount when compared to conventional CT systems at 120 kV.

kn-title=Diacamma ants adjust liquid foraging strategies in response to biophysical constraints
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Ant foragers provide food to the rest of the colony, often requiring transport over long distances. Foraging for liquid is challenging because it is difficult to transport and share. Many social insects store liquids inside the crop to transport them to the nest, and then regurgitate to distribute to nest-mates through a behaviour called trophallaxis. Some ants instead transport fluids with a riskier behaviour called pseudotrophallaxis—holding a drop of liquid between the mandibles through surface tension. Ants share this droplet with nest-mates without ingestion or regurgitation. We hypothesised that ants optimize their liquid-collection approach depending on viscosity. Using an ant that employs both trophallaxis and pseudotrophallaxis, we investigated the conditions where each liquid-collection behaviour is favoured by measuring biophysical properties, collection time and reaction to food quality for typical and viscosity-altered sucrose solutions. We found that ants collected more liquid per unit time by mandibular grabbing than by drinking. At high viscosities ants switched liquid collection method to mandibular grabbing in response to viscosity and not to sweetness. Our results demonstrate that ants change transport and sharing methods according to viscosity–a natural proxy for sugar concentration–thus increasing the mass of sugar returned to the nest per trip.

kn-title=First-principles molecular dynamics simulations for the properties of boron-doped tetrahedral amorphous carbon
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Based on first-principles molecular dynamics (FPMD) simulations combined with a liquid quenching method, we study the effects of boron doping at 0 %, 2 %, 4 %, 6 % on the properties of tetrahedral amorphous carbon (ta-C) with an initial density of 3.0 g/cm3. The results of bond structures and internal stress show the promotion of graphitization with increase in the concentration of boron doping. In addition, simulation of electronic states reveals that the Fermi level shifts to valence band and the intensity of density of electronic states near Fermi level increases with the boron concentration increasing. A covalent bond formation between carbon and boron atoms is also shown by analyzing projected densities of electronic states (PDOS) and electron density distribution. The results of electronic state and bond formation strongly indicate that the boron-doped ta-C is like a p-type semiconductor. The present simulation results provide useful information for deeper understanding on the physical properties of boron-doped ta-C.

kn-title=Inhibition of Amino Acids Influx into Proximal Tubular Cells Improves Lysosome Function in Diabetes
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Inhibition of glucose influx into proximal tubular cells (PTCs) by sodium–glucose cotransporter 2 inhibitors revealed prominent therapeutic effects on diabetic kidney disease. Collectrin (CLTRN) serves as a chaperone for the trafficking of neutral amino acid (AA) transporters in the apical membranes of PTCs. We investigated the beneficial effects of reduced influx of AAs into PTCs in diabetes and obesity model of Cltrn−/y mice.
Methods Cltrn+/y and Cltrn−/y mice at age 5 weeks were assigned to standard diet and streptozotocin and high-fat diet (STZ-HFD)–treated groups.
Results At age 22–23 weeks, body weight and HbA1c levels significantly increased in STZ-HFD-Cltrn+/y compared with standard diet-Cltrn+/y; however, they were not altered in STZ-HFD-Cltrn−/y compared with STZ-HFD-Cltrn+/y. At age 20 weeks, urinary albumin creatinine ratio was significantly reduced in STZ-HFD-Cltrn−/y compared with STZ-HFD-Cltrn+/y. Under the treatments with STZ and HFD, the Cltrn gene deficiency caused significant increase in urinary concentration of AAs such as Gln, His, Gly, Thr, Tyr, Val, Trp, Phe, Ile, Leu, and Pro. In PTCs in STZ-HFD-Cltrn+/y, the enlarged lysosomes with diameter of 10 μm or more were associated with reduced autolysosomes, and the formation of giant lysosomes was prominently suppressed in STZ-HFD-Cltrn−/y. Phospho-mTOR and inactive form of phospho-transcription factor EB were reduced in STZ-HFD-Cltrn−/y compared with STZ-HFD-Cltrn+/y.
Conclusions The reduction of AAs influx into PTCs inactivated mTOR, activated transcription factor EB, improved lysosome function, and ameliorated vacuolar formation of PTCs in STZ-HFD-Cltrn−/y mice.

kn-title=The effect of exogenous dihydroxyacetone and methylglyoxal on growth, anthocyanin accumulation, and the glyoxalase system in Arabidopsis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Dihydroxyacetone (DHA) occurs in wide-ranging organisms, including plants, and can undergo spontaneous conversion to methylglyoxal (MG). While the toxicity of MG to plants is well-known, the toxicity of DHA to plants remains to be elucidated. We investigated the effects of DHA and MG on Arabidopsis. Exogenous DHA at up to 10 mM did not affect the radicle emergence, the expansion of green cotyledons, the seedling growth, or the activity of glyoxalase II, while DHA at 10 mM inhibited the root elongation and increased the activity of glyoxalase I. Exogenous MG at 1.0 mM inhibited these physiological responses and increased both activities. Dihydroxyacetone at 10 mM increased the MG content in the roots. These results indicate that DHA is not so toxic as MG in Arabidopsis seeds and seedlings and suggest that the toxic effect of DHA at high concentrations is attributed to MG accumulation by the conversion to MG.

kn-subtitle=
en-abstract=
kn-abstract=We investigated the effects of a Tankyrase (TNKS-1/2) inhibitor on mechanical stress-induced gene expression in human chondrocytes and examined TNKS-1/2 expression in human osteoarthritis (OA) cartilage. Cells were seeded onto stretch chambers and incubated with or without a TNKS-1/2 inhibitor (XAV939) for 12 h. Uni-axial cyclic tensile strain (CTS) (0.5 Hz, 8% elongation, 30 min) was applied and the gene expression of type II collagen a1 chain (COL2A1), aggrecan (ACAN), SRY-box9 (SOX9), TNKS-1/2, a disintegrin and metalloproteinase with thrombospondin motifs-5 (ADAMTS-5), and matrix metalloproteinase-13 (MMP-13) were examined by real-time PCR. The expression of ADAMTS-5, MMP-13, nuclear translocation of nuclear factor-κB (NF-κB), and β-catenin were examined by immunocytochemistry and Western blotting. The concentration of IL-1β in the supernatant was examined by enzyme-linked immunosorbent assay (ELISA). TNKS-1/2 expression was assessed by immunohistochemistry in human OA cartilage obtained at the total knee arthroplasty. TNKS-1/2 expression was increased after CTS. The expression of anabolic factors were decreased by CTS, however, these declines were abrogated by XAV939. XAV939 suppressed the CTS-induced expression of catabolic factors, the release of IL-1β, as well as the nuclear translocation of NF-κB and β-catenin. TNKS-1/2 expression increased in mild and moderate OA cartilage. Our results demonstrated that XAV939 suppressed mechanical stress-induced expression of catabolic proteases by the inhibition of NF-κB and activation of β-catenin, indicating that TNKS-1/2 expression might be associated with OA pathogenesis.

kn-title=Mutual Effects of Orexin and Bone Morphogenetic Proteins on Catecholamine Regulation Using Adrenomedullary Cells
en-subtitle=

en-abstract=
kn-abstract=Orexins are neuronal peptides that play a prominent role in sleep behavior and feeding behavior in the central nervous system, though their receptors also exist in peripheral organs, including the adrenal gland. In this study, the effects of orexins on catecholamine synthesis in the rat adrenomedullary cell line PC12 were investigated by focusing on their interaction with the adrenomedullary bone morphogenetic protein (BMP)-4. Orexin A treatment reduced the mRNA levels of key enzymes for catecholamine synthesis, including tyrosine hydroxylase (Th), 3,4-dihydroxyphenylalanie decarboxylase (Ddc) and dopamine beta-hydroxylase (Dbh), in a concentration-dependent manner. On the other hand, treatment with BMP-4 suppressed the expression of Th and Ddc but enhanced that of Dbh with or without co-treatment with orexin A. Of note, orexin A augmented BMP-receptor signaling detected by the phosphorylation of Smad1/5/9 through the suppression of inhibitory Smad6/7 and the upregulation of BMP type-II receptor (BMPRII). Furthermore, treatment with BMP-4 upregulated the mRNA levels of OX1R in PC12 cells. Collectively, the results indicate that orexin and BMP-4 suppress adrenomedullary catecholamine synthesis by mutually upregulating the pathway of each other in adrenomedullary cells.

kn-abstract=Genetic factors of yield related traits in lowland New Rice for Africa variety (NERICA) using different nitrogen condition and QTL to increase rice yield in lowland NERICAs were clarified. Indica Group rice variety (Oryza sativa L.) IR64 increased panicle number, culm weight and panicle weight, according to nitrogen concentration. The tendency is especially remarkable under low nitrogen concentration. NERICA‒L‒19, which is derived from a cross between IR64 and TOG5681 (Oryza glaberrima S.), showed similar values for panicle weight and culm weight, and it showed higher plant height, panicle weight and culm weight and lower harvest index than those of IR64 under all the concentrations. QTL analysis for the agronomic traits were performed using hybrid population derived from a cross between IR64 and NERICA‒L‒19. A total of 22 QTLs were detected on chromosomes (chrs.) 1 (3 QTLs), 2 (2), 4 (2), 5 (5), 6 (1), 7 (1), 8 (6) and 10 (2). Among them, 4 regions at 34.1‒36.6Mbp of chr. 1, at 23.8‒27.8Mbp of chr. 5 and at 4.8Mbp and 20.3‒28.4Mbp of chr. 8 showed several QTLs’ peaks overlapped. The regions of chr. 5 and 4.8Mbp of chr. 8 increased panicle weight by IR64 allele. Those of chr. 1 and 20.3-28.4Mbp of chr. 8 increased plant height and harvest index, respectively, by NERICA‒L‒19 allele. These results indicated that the larger panicle type of lowland NERICA is suitable under low nitrogen condition. Also, the plant type was controlled by the combination of 4 QTLs’ regions on chr. 1 and short arm of chr. 8 originated from O. glaberrima, and those of chr. 5 and long arm of chr. 8 from O. sativa Indica Group.

kn-title=pSPICA Force Field Extended for Proteins and Peptides
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Many coarse-grained (CG) molecular dynamics (MD) studies have been performed to investigate biological processes involving proteins and lipids. CG force fields (FFs) in these MD studies often use implicit or nonpolar water models to reduce computational costs. CG-MD using water models cannot properly describe electrostatic screening effects owing to the hydration of ionic segments and thus cannot appropriately describe molecular events involving water channels and pores through lipid membranes. To overcome this issue, we developed a protein model in the pSPICA FF, in which a polar CG water model showing the proper dielectric response was adopted. The developed CG model greatly improved the transfer free energy profiles of charged side chain analogues across the lipid membrane. Application studies on melittin-induced membrane pores and mechanosensitive channels in lipid membranes demonstrated that CG-MDs using the pSPICA FF correctly reproduced the structure and stability of the pores and channels. Furthermore, the adsorption behavior of the highly charged nona-arginine peptides on lipid membranes changed with salt concentration, indicating the pSPICA FF is also useful for simulating protein adsorption on membrane surfaces.

kn-title=Prediction of slip activity of crystal grains around semi-circular and semi-elliptical notches in thin-sheet specimens of pure titanium using formulated macroscopic stress distribution and crystal orientation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Thin metal sheets and wires are important materials for various devices used in electrical, mechanical, and medical fields. With the downsizing of these devices, demand for thinner sheets and wires has increased. Amongst the many metals available, pure titanium has been attracting much attention for use in medical and dental devices because of its good biocompatibility in addition to its light weight and high corrosion resistance. However, thin metal sheets and wires are usually polycrystalline materials and, with the downsizing of materials, there is a loss of homogeneity during deformations. Inhomogeneous deformation becomes significant in thin sheets and wires, owing to the different crystal orientations and geometries of crystal grains. Furthermore, the shapes of such devices are not uniform, unlike, say, a simple rod. Therefore, macroscopic stress and strain concentrations should be taken into consideration when designing these devices as they affect the localization of deformation and the resultant fracture. In this study, semi-circular and semi-elliptical notched specimens made of thin-sheet polycrystalline pure titanium are subjected to tensile testing. Inhomogeneous deformation caused by crystallographic slip is observed near the notch root. Analysis of the crystal orientation and observation of the slip line show that the slip initiation in crystal grains is affected by the macroscopic stress distribution and can be predicted from the slip activity calculated from both the critical resolved shear stress on the slip systems and the resolved shear stress acting on prospective slip planes obtained from the macroscopic multiaxial stress distribution.

kn-title=Relevance of complement immunity with brain fog in patients with long COVID
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction
This study aimed to elucidate the prevalence and clinical characteristics of patients with long COVID (coronavirus disease 2019), especially focusing on 50% hemolytic complement activity (CH50).
Methods
This retrospective observational study focused on patients who visited Okayama University Hospital (Japan) for the treatment of long COVID between February 2021 and March 2023. CH50 levels were measured using liposome immunometric assay (Autokit CH50 Assay, FUJIFILM Wako Pure Chemical Corporation, Japan); high CH50 was defined as ≥59 U/mL. Univariate analyses assessed differences in the clinical background, long COVID symptoms, inflammatory markers, and clinical scores of patients with normal and high CH50. Logistic regression model investigated the association between high CH50 levels and these factors.
Results
Of 659 patients who visited our hospital, 478 patients were included. Of these, 284 (59.4%) patients had high CH50 levels. Poor concentration was significantly more frequent in the high CH50 group (7.2% vs. 13.7%), whereas no differences were observed in other subjective symptoms (fatigue, headache, insomnia, dyspnea, tiredness, and brain fog). Multivariate analysis was performed on factors that could be associated with poor concentration, suggesting a significant relationship to high CH50 levels (adjusted odds ratio [aOR], 2.70; 95% confidence interval [CI], 1.33–5.49). Also, high CH50 was significantly associated with brain fog (aOR, 1.66; 95% CI, 1.04–2.66).
Conclusions
High CH50 levels were frequently reported in individuals with long COVID, indicating a relationship with brain fog. Future in-depth research should examine the pathological role and causal link between complement immunity and the development of long COVID.

kn-title=Attenuation of pulmonary damage in aged lipopolysaccharide-induced inflammation mice through continuous 2 % hydrogen gas inhalation: A potential therapeutic strategy for geriatric inflammation and survival
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: With the global population aging, there is an increased prevalence of sepsis among the elderly, a demographic particularly susceptible to inflammation. This study aimed to evaluate the therapeutic potential of hydrogen gas, known for its anti-inflammatory and antioxidant properties, in attenuating inflammation specifically in the lungs and liver, and age-associated molecular markers in aged mice.
Methods: Male mice aged 21 to 23 months, representative of the human elderly population, were subjected to inflammation via intraperitoneal injection of lipopolysaccharide (LPS). The mice were allocated into eight groups to examine the effects of varying durations and concentrations of hydrogen gas inhalation: control, saline without hydrogen, saline with 24-hour 2 % hydrogen, LPS without hydrogen, LPS with 24-hour 2 % hydrogen, LPS with 6-hour 2 % hydrogen, LPS with 1-hour 2 % hydrogen, and LPS with 24-hour 1 % hydrogen. Parameters assessed included survival rate, activity level, inflammatory biomarkers, and organ injury.
Results: Extended administration of hydrogen gas specifically at a 2 % concentration for 24 h led to a favorable prognosis in the aged mice by reducing mRNA expression of inflammatory biomarkers in lung and liver tissue, mitigating lung injury, and diminishing the expression of the senescence-associated protein p21. Moreover, hydrogen gas inhalation selectively ameliorated senescence-related markers in lung tissue, including C-X-C motif chemokine 2, metalloproteinase-3, and arginase-1. Notably, hydrogen gas did not alleviate LPS-induced liver injury under the conditions tested.
Conclusion: The study highlights that continuous inhalation of hydrogen gas at a 2 % concentration for 24 h can be a potent intervention in the geriatric population for improving survival and physical activity by mitigating pulmonary inflammation and modulating senescence-related markers in aged mice with LPS-induced inflammation. This finding paves the way for future research into hydrogen gas as a therapeutic strategy to alleviate severe inflammation that can lead to organ damage in the elderly.

kn-title=Effects of liquefied sake lees on growth performance and faecal and blood characteristics in Japanese Black calves
en-subtitle=

kn-abstract=Liquefied sake lees, a by-product of Japanese sake, is rich in Saccharomyces cerevisiae, proteins, and prebiotics derived from rice and yeast. Previous studies have reported that Saccharomyces cerevisiae fermentation products improved the health, growth, and faecal characteristics of preweaning calves. This study investigated the effects of adding liquefied sake lees to milk replacer on the growth performance, faecal characteristics, and blood metabolites of preweaning Japanese Black calves from 6 to 90 days of age. Twenty-four Japanese Black calves at 6 days of age were randomly assigned to one of three treatments: No liquefied sake lees (C, n = 8), 100 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (LS, n = 8), and 200 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (HS, n = 8). The intake of milk replacer and calf starter, as well as, the average daily gain did not differ between the treatments. The number of days counted with faecal score 1 in LS was higher than in HS (P < 0.05), while the number of days with diarrhoea medication in LS and C was lower than HS (P < 0.05). The faecal n-butyric acid concentration tended to be higher in LS compared to C (P = 0.060). The alpha diversity index (Chao1) was higher in HS than in C and LS at 90 days of age (P < 0.05). The principal coordinate analysis (PCoA) using weighted UniFrac distance showed that the bacterial community structures in faeces among the treatments at 90 days of age were significantly different (P < 0.05). The plasma β-hydroxybutyric acid concentration, an indicator of rumen development, was higher for LS than in C throughout the experiment (P < 0.05). These results suggested that adding liquefied sake lees up to 100 g/d (on a fresh matter basis) might promote rumen development in preweaning Japanese Black calves.

kn-title=Effects of Nutritional Support Combined with Neuromuscular Electrical Stimulation on Muscle Strength and Thickness: A Randomized Controlled Trial in Healthy Young Adult Males
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In the management of post-injury patients with activity limitations, methods to prevent musculoskeletal disorders and hasten recovery are important. This randomized controlled, single-blinded study was a preliminary investigation of the combined effect of nutritional support with neuromuscular electrical stimulation (NMES) on muscle strength and thickness. Healthy young adult males (median age, 21 years) were enrolled; each of their hands was randomly assigned to one of the following four groups: Placebo, Nutrition, NMES, and Nutrition + NMES. All participants received whey protein or placebo (3x/week for 6 weeks) and NMES training (3x/week for 6 weeks) on the abductor digiti minimi (ADM) muscle of either the left or right hand. ADM muscle strength and thickness were analyzed at baseline and at week 7. We analyzed 38 hands (9 Placebo, 10 Nutrition, 9 NMES, 10 Nutrition + NMES). There was significantly greater muscle strengthening in the Nutrition + NMES group compared to the Placebo group or the NMES group, but no significant difference in gain of muscle thickness. The combined intervention may be effective in improving muscle strength. Future clinical trials targeting various muscles after sports-related injuries are warranted.

kn-title=Concomitant Use of Multiple Nephrotoxins including Renal Hypoperfusion Medications Causes Vancomycin-Associated Nephrotoxicity: Combined Retrospective Analyses of Two Real-World Databases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=There is a growing concern about the relationship between vancomycin-associated nephrotoxicity (VAN) and concomitant use of nephrotoxins. We examined this relationship by combined retrospective analyses of two real-world databases. Initially, the FDA Adverse Event Reporting System (FAERS) was analyzed for the effects of concomitant use of one or more nephrotoxins on VAN and the types of combinations of nephrotoxins that exacerbate VAN. Next, electronic medical records (EMRs) of patients who received vancomycin (VCM) at Tokushima University Hospital between January 2006 and March 2019 were examined to confirm the FAERS analysis. An elevated reporting odds ratio (ROR) was observed with increases in the number of nephrotoxins administered (VCM + one nephrotoxin, adjusted ROR (95% confidence interval [CI]) 1.67 [1.51-1.85]; VCM + ≥2 nephrotoxins, adjusted ROR [95% CI] 1.54 [1.37-1.73]) in FAERS. EMRs analysis showed that the number of nephrotoxins was associated with higher incidences of VAN [odds ratio: 1.99; 95% CI: 1.42-2.78]. Overall, concomitant use of nephrotoxins was associated with an increased incidence of VAN, especially when at least one of those nephrotoxins was a renal hypoperfusion medication (furosemide, non-steroidal anti-inflammatory drugs, and vasopressors). The concomitant use of multiple nephrotoxins, especially including renal hypoperfusion medication, should be avoided to prevent VAN.

kn-title=Analysis of Evaporation of Droplet Pairs by a Quasi-Steady-State Diffusion Model Coupled with the Evaporative Cooling Effect
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Multidroplet evaporation is a common phase-change phenomenon not only in nature but also in many industrial applications, including inkjet printing and spray cooling. The evaporation behavior of these droplets is strongly affected by the distance between neighboring droplets, and in particular, evaporation suppression occurs as the distance decreases. However, further quantitative information, such as the temperature and local evaporation flux, is limited because the analytical models of multidroplet evaporation only treat vapor diffusion, and the effect of the latent heat transfer through the liquid–vapor phase change is ignored. Here, we perform a numerical analysis of evaporating droplet pairs that linked vapor diffusion from the droplet surface and evaporative cooling. Heat transfer through the liquid and gas phases is also considered because the saturation pressure depends on the temperature. The results show an increase in the vapor concentration in the region between the two droplets. Consequently, the local evaporation flux in the proximate region significantly decreases with decreasing separation distance. This means that the latent heat transfer through the phase change is diminished, and an asymmetrical temperature distribution occurs in the liquid and gas phases. These numerical results provide quantitative information about the temperature and local evaporation flux of evaporating droplet pairs, and they will guide further investigation of multiple droplet evaporation.

kn-title=High hydrostatic pressure induces slow contraction in mouse cardiomyocytes
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Cardiomyocytes are contractile cells that regulate heart contraction. Ca2+ flux via Ca2+ channels activates actomyosin interactions, leading to cardiomyocyte contraction, which is modulated by physical factors (e.g., stretch, shear stress, and hydrostatic pressure). We evaluated the mechanism triggering slow contractions using a high-pressure microscope to characterize changes in cell morphology and intracellular Ca2+ concentration ([Ca2+]i) in mouse cardiomyocytes exposed to high hydrostatic pressures. We found that cardiomyocytes contracted slowly without an acute transient increase in [Ca2+]i, while a myosin ATPase inhibitor interrupted pressure-induced slow contractions. Furthermore, transmission electron microscopy showed that, although the sarcomere length was shortened upon the application of 20 MPa, this pressure did not collapse cellular structures such as the sarcolemma and sarcomeres. Our results suggest that pressure-induced slow contractions in cardiomyocytes are driven by the activation of actomyosin interactions without an acute transient increase in [Ca2+]i.

In this study, we found that a population of connective tissue mast cells (CTMCs) stores and releases noradrenaline, originating from sympathetic nerves. Noradrenaline-storing cells, not neuronal fibers, were predominantly identified in the connective tissues of the skin, mammary gland, gastrointestinal tract, bronchus, thymus, and pancreas in wild-type mice but were absent in mast cell-deficient W-sash c-kit mutant KitW-sh/W-sh mice. In vitro studies using bone marrow-derived mast cells revealed that extracellular noradrenaline was taken up but not synthesized. Upon ionomycin stimulation, noradrenaline was released. Electron microscopy analyses further suggested that noradrenaline is stored in and released from the secretory granules of mast cells. Finally, we found that noradrenaline-storing CTMCs express organic cation transporter 3 (Oct3), which is also known as an extraneuronal monoamine transporter, SLC22A3. Our findings indicate that mast cells may play a role in regulating noradrenaline concentration by storing and releasing it in somatic tissues.

kn-title=Ruxolitinib altered IFN-β induced necroptosis of human dental pulp stem cells during osteoblast differentiation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Objective: This study aimed to evaluate the role of ruxolitinib in the interferon beta (IFN-β) mediated osteoblast differentiation using human dental pulp stem cells (hDPSCs).
Design: hDPSCs from five deciduous teeth of healthy patients were stimulated by adding human recombinant IFN-β protein (1 or 2 ng/ml) to the osteogenic differentiation induction medium. Substrate formation was determined using Alizarin Red staining, calcium concentration, and osteoblast marker expression levels. Ruxolitinib was used to inhibit the Janus kinase/signal transducers and activators of transcription (JAK-STAT) pathway. Apoptosis was detected using terminal deoxynucleotidyl nick-end labeling (TUNEL) staining, and necroptosis was detected using propidium iodide staining and phosphorylated mixed lineage kinase domain-like protein (pMLKL) expression.
Results: In the IFN-β-treated group, substrate formation was inhibited by a reduction in alkaline phosphatase (ALP) expression in a concentration-dependent manner. Although the proliferation potency was unchanged between the IFN-β-treated and control groups, the cell number was significantly reduced in the experimental group. TUNEL-positive cell number was not significantly different; however, the protein level of necroptosis markers, interleukin-6 (IL-6) and pMLKL were significantly increased in the substrate formation. Cell number and ALP expression level were improved in the group administered ruxolitinib, a JAK-STAT inhibitor. Additionally, ruxolitinib significantly suppressed IL-6 and pMLKL levels.
Conclusion: Ruxolitinib interfered with the IFN-β-mediated necroptosis and osteogenic differentiation via the JAK-STAT pathway.

kn-title=Relative stereochemical determination of the C61–C83 fragment of symbiodinolide using a stereodivergent synthetic approach
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Structural determination is required in the use of marine natural products to create novel drugs and drug leads in medicinal chemistry. Symbiodinolide, which is a polyol marine natural product with a molecular weight of 2860, increases the intracellular Ca2+ concentration and exhibits inhibitory activity against cyclooxygenase-1. Seventy percent of the structure of symbiodinolide has been stereochemically clarified. Herein, we report the elucidation of the relative configuration of the C61–C83 fragment, which is among the remaining thirty percent, using a stereodivergent synthetic strategy. We first assigned the relative configuration of the C61–C74 fragment. Two candidate diastereomers of the C61–C74 fragment were synthesized, and their NMR data were compared with those of the natural product, revealing the relative stereochemistry of this component. We then narrowed down the candidate compounds for the C69–C83 fragment from 16 possible diastereomers by analyzing the NMR data of the natural product, and we thus selected eight candidate diastereomers. Stereodivergent synthesis of the candidates for this fragment and comparison of the NMR data of the natural product and the eight synthetic products resulted in the relative stereostructural clarification of the C69–C83 fragment. These individually determined relative stereochemistries of the C61–C74 and C69–C83 fragments were connected via the common C69–C73 tetrahydropyran moiety of the fragments. Finally, the relative configuration of the C61–C83 fragment of symbiodinolide was determined. The stereodivergent synthetic approach used in this study can be extended to the stereochemical determination of other fragments of symbiodinolide.

kn-title=A tonoplast‐localized magnesium transporter is crucial for stomatal opening in Arabidopsis under high Mg2+ conditions
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Plant stomata play an important role in CO2 uptake for photosynthesis and transpiration, but the mechanisms underlying stomatal opening and closing under changing environmental conditions are still not completely understood.
Through large-scale genetic screening, we isolated an Arabidopsis mutant (closed stomata2 (cst2)) that is defective in stomatal opening. We cloned the causal gene (MGR1/CST2) and functionally characterized this gene.
The mutant phenotype was caused by a mutation in a gene encoding an unknown protein with similarities to the human magnesium (Mg2+) efflux transporter ACDP/CNNM. MGR1/CST2 was localized to the tonoplast and showed transport activity for Mg2+. This protein was constitutively and highly expressed in guard cells. Knockout of this gene resulted in stomatal closing, decreased photosynthesis and growth retardation, especially under high Mg2+ conditions, while overexpression of this gene increased stomatal opening and tolerance to high Mg2+ concentrations. Furthermore, guard cell-specific expression of MGR1/CST2 in the mutant partially restored its stomatal opening.
Our results indicate that MGR1/CST2 expression in the leaf guard cells plays an important role in maintaining cytosolic Mg2+ concentrations through sequestering Mg2+ into vacuoles, which is required for stomatal opening, especially under high Mg2+ conditions.

kn-subtitle=
en-abstract=
kn-abstract=We report the first search result for the flux of astrophysical electron antineutrinos for energies O(10) MeV in the gadolinium-loaded Super-Kamiokande (SK) detector. In 2020 June, gadolinium was introduced to the ultrapure water of the SK detector in order to detect neutrons more efficiently. In this new experimental phase, SK-Gd, we can search for electron antineutrinos via inverse beta decay with efficient background rejection thanks to the high efficiency of the neutron tagging technique. In this paper, we report the result for the initial stage of SK-Gd, during 2020 August 26, and 2022 June 1 with a 22.5 x 552 kton center dot day exposure at 0.01% Gd mass concentration. No significant excess over the expected background in the observed events is found for the neutrino energies below 31.3 MeV. Thus, the flux upper limits are placed at the 90% confidence level. The limits and sensitivities are already comparable with the previous SK result with pure water (22.5 x 2970 kton center dot day) owing to the enhanced neutron tagging. Operation with Gd increased to 0.03% started in 2022 June.

kn-title=Evidence for Hypoxia-Induced Shift in ATP Production from Glycolysis to Mitochondrial Respiration in Pulmonary Artery Smooth Muscle Cells in Pulmonary Arterial Hypertension
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: The metabolic state of pulmonary artery smooth muscle cells (PASMCs) from patients with pulmonary arterial hypertension (PAH) is not well understood. In this study, we examined the balance between glycolysis and mitochondrial respiration in non-PAH-PASMCs and PAH-PASMCs under normoxia and hypoxia. Methods: We investigated the enzymes involved in glycolysis and mitochondrial respiration, and studied the two major energy-yielding pathways (glycolysis and mitochondrial respiration) by measuring extracellular acidification rate (ECAR) and cellular oxygen consumption rate (OCR) using the Seahorse extracellular flux technology. Results: Under both normoxia and hypoxia, the mRNA and protein levels of pyruvate dehydrogenase kinase 1 and pyruvate dehydrogenase were increased in PAH-PASMCs compared with non-PAH-PASMCs. The mRNA and protein levels of lactate dehydrogenase, as well as the intracellular lactate concentration, were also increased in PAH-PASMCs compared with non-PAH-PASMCs under normoxia. However, these were not significantly increased in PAH-PASMCs compared with non-PAH-PASMCs under hypoxia. Under normoxia, ATP production was significantly lower in PAH-PASMCs (59 ± 5 pmol/min) than in non-PAH-PASMCs (70 ± 10 pmol/min). On the other hand, ATP production was significantly higher in PAH-PASMCs (31 ± 5 pmol/min) than in non-PAH-PASMCs (14 ± 3 pmol/min) under hypoxia. Conclusions: There is an underlying change in the metabolic strategy to generate ATP production under the challenge of hypoxia.

kn-title=Association of Tumor Necrosis Factor-Alpha with Psychopathology in Patients with Schizophrenia
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We investigated the relationship between serum tumor necrosis factor-alpha (TNF-α) levels and psychopathological symptoms, clinical and socio-demographic characteristics and antipsychotic therapy in individuals with schizophrenia. TNF-α levels were measured in 90 patients with schizophrenia and 90 healthy controls matched by age, gender, smoking status, and body mass index. The Positive and Negative Syndrome Scale (PANSS) was used to assess the severity of psychopathology in patients. No significant differences in TNF-α levels were detected between the patients and controls (p=0.736). TNF-α levels were not correlated with total, positive, negative, general, or composite PANSS scores (all p>0.05). A significant negative correlation was observed between TNF-α levels and the PANSS cognitive factor (ρ=−0.222, p=0.035). A hierarchical regression analysis identified the cognitive factor as a significant predictor of the TNF-α level (beta=−0.258, t=−2.257, p=0.027). There were no significant differences in TNF-α levels among patients treated with different types of antipsychotics (p=0.596). TNF-α levels correlated positively with the age of onset (ρ=0.233, p=0.027) and negatively with illness duration (ρ=−0.247, p=0.019) and antipsychotic treatment duration (ρ=−0.256, p=0.015). These results indicate that TNF-α may be involved in cognitive impairment in schizophrenia, and would be a potential clinical-state marker in schizophrenia.

kn-title=Association between Radon Hot Spring Bathing and Health Conditions: A Cross-Sectional Study in Misasa, Japan
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=No epidemiological studies have examined the health effects of daily bathing in radon hot springs. In this cross-sectional study, we investigated the associations between radon hot spring bathing and health conditions. The target population was 5,250 adults ≥ 20 years old in the town of Misasa, Japan. We collected information about the participants’ bathing habits and alleviation of a variety of disease symptoms, and their self-rated health (SRH). Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated. In both the adjusted and unadjusted models of hypertension, significant associations between the > 1×/week hot spring bathing and the alleviation of hypertension symptoms were observed compared to the group whose hot spring bathing was <1×/week: adjusted model, OR 5.40 (95%CI: 1.98-14.74); unadjusted model, 3.67 (1.50-8.99) and for gastroenteritis: adjusted model, 9.18 (1.15-72.96); unadjusted model, 7.62 (1.59-36.49). Compared to the no-bathing group, higher SRH was significantly associated with both bathing < 1×/week: unadjusted model, 2.27 (1.53-3.37) and > 1×/week: adjusted model, 1.91 (1.15-3.19). These findings suggest that bathing in radon hot springs is associated with higher SRH and the alleviation of hypertension and gastroenteritis.

kn-title=Enhanced Production of EPA-Derived Anti-Inflammatory Metabolites after Oral Administration of a Novel Self-Emulsifying Highly Purified EPA Ethyl Ester Formulation (MND-2119)
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Aims: MND-2119 is a novel once-daily dose self-emulsifying formulation of highly purified eicosapentaenoic acid ethyl ester (EPA-E) and is approved as an antihyperlipidemia agent in Japan. It has improved absorption and achieves higher plasma EPA concentrations at Cmax than conventional EPA-E. In the JELIS trial, concomitant use of EPA-E with statin therapy significantly reduced atherosclerotic cardiovascular disease (ASCVD) risks. As a potential mechanism of action of EPA, endogenous formation of EPA-derived anti-inflammatory metabolites is receiving greater attention. This study aims to investigate the endogenous formation of EPA-derived anti-inflammatory metabolites following single and multiple administrations of MND-2119.
Methods: Healthy adult male subjects were randomly assigned to a nonintervention (control) group, MND-2119 2-g/day group, MND-2119 4-g/day group, or EPA-E 1.8-g/day group for 7 days (N=8 per group). Plasma fatty acids and EPA-derived metabolites were evaluated. Peripheral blood neutrophils were isolated, and the production of EPA-derived metabolites from in vitro stimulated neutrophils was evaluated.
Results: After single and multiple administrations of MND-2119 2 g/day, there were significant increases in plasma EPA concentration, 18-hydroxyeicosapentaenoic acid (18-HEPE), and 17,18-epoxyeicosatetraenoic acid compared with those of EPA-E 1.8 g/day. They were further increased with MND-2119 4 g/day administration. In neutrophils, the EPA concentration in the MND-2119 2-g/day group was significantly higher compared with that in the EPA-E 1.8-g/day group after multiple administration, and 18-HEPE production was positively correlated with EPA concentration. No safety issues were noted.
Conclusions: These results demonstrate that MND-2119 increases the plasma and cellular concentrations of EPA and EPA-derived metabolites to a greater extent than conventional EPA-E formulations.

kn-title=Safety and usefulness of nebulized liposomal amphotericin B: Systematic scoping review
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose
Invasive fungal infections potentially result in fatal outcomes in immunocompromised hosts. Compared to intravenous administration, a nebulization therapy can achieve a high concentration of drug delivered in the respiratory tract, without a systematic absorption. We herein summarized the study findings on the safety and clinical utility of nebulized liposomal amphotericin B therapy.
Methods
According to the PRISMA Extension for Scoping Reviews, we performed a search on MEDLINE and EMBASE for articles with relevant keywords, including “inhaled liposomal amphotericin B″, “nebulized liposomal amphotericin B″, or “aerosolized liposomal amphotericin B″, from the inception of these databases to August 31, 2022.
Results
Of the 172 articles found, 27 articles, including 13 case reports, 11 observational studies, and 3 clinical trials, were selected. Generally, findings showed that nebulized liposomal amphotericin B treatment appeared to be safe and without severe adverse effects. We found an accumulated evidence for the safety, tolerability, and effectiveness of nebulized liposomal amphotericin B prophylaxis among lung transplantation recipients; however, a randomized controlled study has yet to be reported. Data on hemato-oncological patients are relatively scarce; however, a randomized controlled study suggested the prophylactic effect of nebulized liposomal amphotericin B on invasive pulmonary aspergillosis. Observational and randomized controlled studies to evaluate therapeutic efficacy of the nebulized liposomal amphotericin B therapy have not been performed.
Conclusion
In conclusion, we found increasing evidence for the effectiveness of the inhalation therapy among patients after lung transplantation and with hemato-oncological diseases.

kn-title=Relationships of rapid eating with visceral and subcutaneous fat mass and plasma adiponectin concentration
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Rapid eating has been demonstrated to be associated with obesity and overweight. However, few studies have characterized the separate relationships of eating speed with visceral and subcutaneous fat mass or circulating adiponectin concentration. We hypothesized that rapid eating is associated with the larger visceral fat tissue (VFT) area and lower adiponectin concentration, but not with the subcutaneous fat tissue (SFT) area in men and women. We performed a cross-sectional study of 712 adults aged 20–86 years (528 men and 184 women; mean ± SD age 59.36 ± 13.61 years). The participants completed a self-reported questionnaire, and underwent anthropometric and laboratory measurements and computed tomographic imaging of the abdomen as a part of annual medical check-ups. Multivariate linear regression analyses revealed that rapid eating was associated with larger visceral (B = 24.74; 95% CI 8.87–40.61, p = 0.002) and subcutaneous fat areas (B = 31.31; 95% CI 12.23–50.38, p = 0.001), lower adiponectin concentration (B = − 2.92; 95% CI − 4.39– − 1.46, p < 0.001), higher body mass index (BMI) (B = 2.13; 95% CI 1.02–3.25, p < 0.001), and larger waist circumference (B = 5.23; 95% CI 2.16–8.30, p < 0.001) in men, which is partially consistent with the hypothesis. In contrast, rapid eating was found to be associated only with BMI, and not with abdominal adipose area or adiponectin concentration in women, which is a result that is not consistent with the hypothesis. These results suggest that there is no difference in the association of rapid eating with VFT and SFT areas.

kn-title=Pivotal role for S-nitrosylation of DNA methyltransferase 3B in epigenetic regulation of tumorigenesis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=DNA methyltransferases (DNMTs) catalyze methylation at the C5 position of cytosine with S-adenosyl-l-methionine. Methylation regulates gene expression, serving a variety of physiological and pathophysiological roles. The chemical mechanisms regulating DNMT enzymatic activity, however, are not fully elucidated. Here, we show that protein S-nitrosylation of a cysteine residue in DNMT3B attenuates DNMT3B enzymatic activity and consequent aberrant upregulation of gene expression. These genes include Cyclin D2 (Ccnd2), which is required for neoplastic cell proliferation in some tumor types. In cell-based and in vivo cancer models, only DNMT3B enzymatic activity, and not DNMT1 or DNMT3A, affects Ccnd2 expression. Using structure-based virtual screening, we discovered chemical compounds that specifically inhibit S-nitrosylation without directly affecting DNMT3B enzymatic activity. The lead compound, designated DBIC, inhibits S-nitrosylation of DNMT3B at low concentrations (IC50 <= 100nM). Treatment with DBIC prevents nitric oxide (NO)-induced conversion of human colonic adenoma to adenocarcinoma in vitro. Additionally, in vivo treatment with DBIC strongly attenuates tumor development in a mouse model of carcinogenesis triggered by inflammation-induced generation of NO. Our results demonstrate that de novo DNA methylation mediated by DNMT3B is regulated by NO, and DBIC protects against tumor formation by preventing aberrant S-nitrosylation of DNMT3B.

kn-title=Low-Oxygen Responses of Cut Carnation Flowers Associated with Modified Atmosphere Packaging
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Gaseous factors affect post-harvest physiological processes in horticultural crops, including ornamental flowers. However, the molecular responses of cut flowers to the low-oxygen conditions associated with modified atmosphere packaging (MAP) have not yet been elucidated. Here, we show that storage of cut carnation flowers in a sealed polypropylene bag decreased the oxygen concentration in the bag to 3-5% and slowed flower opening. The vase life of carnation flowers after storage for seven days under MAP conditions was comparable to that without storage and was improved by the application of a commercial-quality preservative. The adenylate energy charge (AEC) was maintained at high levels in petals from florets stored under MAP conditions. This was accompanied by the upregulation of four hypoxia-related genes, among which the HYPOXIA-RESPONSIVE ETHYLENE RESPONSE FACTOR and PHYTOGLOBIN genes (DcERF19 and DcPGB1) were newly identified. These results suggest that hypoxia-responsive genes contribute to the maintenance of the energy status in carnation flowers stored under MAP conditions, making this gas-controlling technique potentially effective for maintaining cut flower quality without cooling.

kn-title=Lithium-Ion Dynamics in Sulfolane-Based Highly Concentrated Electrolytes
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Here, we report the use of molecular dynamics simulations with a polarizable force field to investigate Li-ion dynamics in sulfolane (SL)-based electrolytes. In SL-based highly concentrated electrolytes (HCEs) (e.g., SL/Li = 2:1), Li displays faster translational motion than other components, which should be related to the structural and dynamical properties of SL. In HCEs, a transient conduction network that penetrated the simulation system was always observed. Rapid (<1 ns) Li-ion hopping between adjacent coordination sites was observed throughout the network. Additionally, SLs rotated in the same timeframe without disrupting the conduction network. This rotation is believed to promote the hopping diffusion in the network. This was followed by a rotational relaxation of the SL dipole axis around the non-polar cyclohydrocarbon segment of SL (∼3.3 ns), which involves a reorganization of the network structure and an enhancement of the translational motion of the coordinating Li ions. The observed lifetime of Li–SL coordination was longer (>11 ns). Hence, it was concluded that the faster Li translational motion was obtained due to the faster rotational relaxation time of SL rather than the lifetime of Li–SL binding. The faster rotation of SL is related to its amphiphilic molecular structure with compact non-polar segments. Transport properties, such as the Onsager transport coefficients, ionic conductivity, and transference number under anion-blocking conditions, were also analyzed to characterize the features of the SL-based electrolyte.

kn-title=Development of Pipetteless Paper-Based Analytical Devices with a Volume Gauge
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this work, we propose a new design for paper based analytical devices (PADs) that eliminate the need to use a micropipette for sample introduction. With this design, a PAD is equipped with a distance-based detection channel that is connected to a storage channel that indicates the volume of a sample introduced into the PAD. The analyte in the sample solution reacts with a colorimetric reagent deposited into the distance-based detection channel as the sample solution flows into the storage channel where the volume is measured. The ratio of the lengths of the detection channel and that of the storage channel (D/S ratio) are constant for a sample containing a certain concentration, which is independent of the introduced volume. Therefore, the PADs permit volume-independent quantification using a dropper instead of a micropipette because the length of the storage channel plays the role of a volume gauge to estimate the introduced sample volume. In this study, the D/S ratios obtained with a dropper were comparable to those obtained with a micropipette, which confirmed that precise volume control is unnecessary for this PAD system. The proposed PADs were applied to the determinations of iron and bovine serum albumin using bathophenanthroline and tetrabromophenol blue as colorimetric reagents, respectively. The calibration curves showed good linear relationships with coefficients of 0.989 for iron and 0.994 for bovine serum albumin, respectively.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The Span 40 (sorbitan monooleate)/Tween 40 (polyoxyethylene sorbitan monolaurate) system gives faceted vesicles with angular surfaces, rather than spherical vesicles. Herein, a continuous and facile preparation method, based on the subcritical water-assisted emulsification and solvent diffusion, was presented to yield faceted vesicles with two major and minor axes (Type A) and vesicles closer to a polyhedron (Type B). Type A, rather than Type B, vesicles were likely to be formed. From the measurements concerning & zeta;-potential, membrane fluidity, and the polarization environment of the membranes, faceted vesicles could be obtained at 0.25 wt% of the surfactant concentration. The phase-separated behavior of Span 40 and Tween 40 within vesicle membranes could explain the structural feature of faceted vesicles and calcein leakage behavior. The significant advantage is that Type A vesicles would be utilized as alternative drug carriers for others with low encapsulation efficiency, although the present technical limitations cause difficulty in the selective formation of Type A and B vesicles and the selection of adequate solvent to accelerate the solvent diffusion step.

kn-title=Efficient granulocyte collection method using high concentrations of medium molecular weight hydroxyethyl starch
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Granulocyte transfusion therapy is a rational therapeutic option for patients with prolonged, severe neutropenia. Although high molecular weight hydroxyethyl starch (hHES) facilitates the separation of red blood cells during granulocyte collection, renal dysfunction has been noted as a potential side effect. HES130/0.4 (Voluven®) is a medium molecular weight HES (mHES) with superior safety profiles compared to hHES. Although HES130/0.4 is reportedly effective in the collection of granulocytes, we lack studies comparing the efficiency of granulocyte collection using HES130/0.4 and hHES.
Study Design and Methods: We retrospectively collected the data from 60 consecutive apheresis procedures performed on 40 healthy donors at the Okayama University Hospital between July 2013 and December 2021. All procedures were performed using the Spectra Optia system. Based on the HES130/0.4 concentration in the separation chamber, granulocyte collection methods using HES130/0.4 were classified into m0.46, m0.44, m0.37, and m0.8 groups. We used HES130/0.4 and hHES groups to compare the various sample collection methods.
Results: The median granulocyte collection efficiency (CE) was approximately 24.0% and 28.1% in the m0.8 and hHES groups, respectively, which were significantly higher than those in the m0.46, m0.44, and m0.37 groups. One month following granulocyte collection with HES130/0.4, no significant changes were observed in serum creatinine levels compared to those before the donation.
Conclusion: Therefore, we propose a granulocyte collection approach employing HES130/0.4, which is comparable to the use of hHES in terms of the granulocyte CE. A high concentration of HES130/0.4 in the separation chamber was considered crucial for granulocyte collection.

kn-title=Hydrogen inhalation attenuates lung contusion after blunt chest trauma in mice
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Lung contusion caused by blunt chest trauma evokes a severe inflammatory reaction in the pulmonary parenchyma that may be associated with acute respiratory distress syndrome. Although hydrogen gas has antioxidant and anti-inflammatory effects and is protective against multiple types of lung injury at safe concentrations, the effects of inhaled hydrogen gas on blunt lung injury have not been previously investigated. Therefore, using a mouse model, we tested the hypothesis that hydrogen inhalation after chest trauma would reduce pulmonary inflammation and acute lung injury associated with lung contusion.
Methods: Inbred male C57BL/6 mice were randomly divided into 3 groups: sham with air inhalation, lung contusion with air inhalation, and lung contusion with 1.3% hydrogen inhalation. Experimental lung contusion was induced using a highly reproducible and standardized apparatus. Immediately after induction of lung contusion, mice were placed in a chamber exposed to 1.3% hydrogen gas in the air. Histopathological analysis and real-time polymerase chain reaction in lung tissue and blood gas analysis were performed 6 hours after contusion.
Results: Histopathological examination of the lung tissue after contusion revealed perivascular/intra-alveolar hemorrhage, perivascular/interstitial leukocyte infiltration, and interstitial/intra-alveolar edema. These histological changes and the extent of lung contusion, as determined by computed tomography, were significantly mitigated by hydrogen inhalation. Hydrogen inhalation also significantly reduced inflammatory cytokine and chemokine mRNA levels and improved oxygenation.
Conclusion: Hydrogen inhalation therapy significantly mitigated inflammatory responses associated with lung contusion in mice. Hydrogen inhalation therapy may be a supplemental therapeutic strategy for treating lung contusion.

kn-title=Modulatory Effects of A1 Milk, A2 Milk, Soy, and Egg Proteins on Gut Microbiota and Fermentation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Milk can be divided into A1 and A2 types according to fi-casein variants, and there is a debate about whether A1 milk consumption exacerbates gut environments. This study examined the cecum microbiota and fermentation in mice fed A1 casein, A2 casein, mixed casein (commercial casein), soy protein isolate, and egg white. The cecum acetic acid concentration was higher, and the relative abundances of Muribaculaceae and Desulfovibrionaceae were greater in mice fed A1 versus A2 casein. The other parameters of cecum fermentation and microbiota composition were similar among the mice fed A1, A2, and mixed caseins. The differences were more distinctive among the three caseins, soy, and egg feedings. Chao 1 and Shannon indices of the cecum microbiota were lowered in egg white-fed mice, and the microbiota of mice fed milk, soy, and egg proteins were separately grouped by principal coordinate analysis. Mice fed the three caseins were characterized by a high abundance of Lactobacillaceae and Clostridiaceae, those fed soy were characterized by Corynebacteriaceae, Muribaculaceae, and Ruminococcaceae, and those fed egg white were characterized by Eggerthellaceae, Rikenellaceae, and Erysipelatoclostridiaceae. Thus, although several differences can arise between A1 and A2 caseins in terms of their modulatory effects on gut environments, the differences between milk, soy, and egg proteins can be more distinctive and are worth further consideration.

kn-title=ATP and its metabolite adenosine cooperatively upregulate the antigen-presenting molecules on dendritic cells leading to IFN-gamma production by T cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Dendritic cells (DCs) present foreign antigens to T cells via the major histocompatibility complex (MHC), thereby inducing acquired immune responses. ATP accumulates at sites of inflammation or in tumor tissues, which triggers local inflammatory responses. However, it remains to be clarified how ATP modulates the functions of DCs. In this study, we investigated the effects of extracellular ATP on mouse bone marrow- derived dendritic cells (BMDCs) as well as the potential for subsequent T cell activation. We found that high concentrations of ATP (1 mM) upregulated the cell surface expression levels of MHC-I, MHC-II, and co-stimulatory molecules CD80 and CD86 but not those of co-inhibitory molecules PD-L1 and PD-L2 in BMDCs. Increased surface expression of MHC-I, MHC-II, CD80, and CD86 was inhibited by a pan-P2 receptor antagonist. In addition, the upregulation of MHC-I and MHC-II expression was inhibited by an adenosine P1 receptor antagonist and by inhibitors of CD39 and CD73, which metabolize ATP to adenosine. These results suggest that adenosine is required for the ATP-induced upregulation of MHC-I and MHC-II. In the mixed leukocyte reaction assay, ATP-stimulated BMDCs activated CD4 and CD8T cells and induced interferon-gamma (IFN-gamma) production by these T cells. Collectively, these results suggest that high concentrations of extracellular ATP upregulate the expression of antigenpresenting and co-stimulatory molecules but not that of coinhibitory molecules in BMDCs. Cooperative stimulation of ATP and its metabolite adenosine was required for the upregulation of MHC-I and MHC-II. These ATP-stimulated BMDCs induced the activation of IFN-gamma-producing T cells upon antigen presentation.

en-abstract=
kn-abstract=Changes in hormone levels in patients with cancer cachexia after anamorelin administration have not been fully investigated. This study aimed to determine how anamorelin affects the endocrine system in patients with gastrointestinal cancer and cachexia. We prospectively enrolled 13 patients and comprehensively investigated their body weight and levels of serum albumin, hemoglobin A1c (HbA1c), and hormones before (week 0) and 3 and 12 weeks after anamorelin administration. The variables were evaluated at week 3 in 9 patients and at week 12 in 5 patients. At week 3, anamorelin administration resulted in body weight gain and increased the levels of growth hormone and HbA1c, as well as insulin-like growth factor-1 standard deviation scores (IGF-1 SD scores). At the same time, negative correlations were observed between ΔIGF-1 SD score and Δthyroidstimulating hormone (TSH) and between ΔIGF-1 SD score and Δfree testosterone. ΔBody weight and ΔIGF-1 SD score correlated positively at week 12. These results suggest that TSH and free testosterone levels can be affected 3 weeks after anamorelin administration; however, those variables tend to return to a state of equilibrium, and anabolic effects of anamorelin appear in long-term (≥ 12 weeks) users.

en-abstract=
kn-abstract=Dexmedetomidine (DEX) can reduce lung injury in a hemorrhagic shock (HS) resuscitation (HSR) model in rats by inhibiting inflammation. Here, we aimed to investigate if these effects of DEX are due to autophagy activation. Therefore, we established HSR rat models and divided them into four groups. HS was induced using a blood draw. The rats were then resuscitated by reinjecting the drawn blood and saline. The rats were sacrificed 24 h after resuscitation. Lung tissues were harvested for histopathological examination, determination of wet/dry lung weight ratio, and detection of the levels of autophagy-related marker proteins LC3, P62, Beclin-1, and the ATG12-ATG5 conjugate. The morphological findings of hematoxylin and eosin staining in lung tissues and the pulmonary wet/dry weight ratio showed that lung injury improved in HSR + DEX rats. However, chloroquine (CQ), an autophagy inhibitor, abolished this effect. Detecting the concentration of autophagy-related proteins showed that DEX administration increased LC3, ATG12-ATG5, and Beclin-1 expression and decreased P62 expression. The expression levels of these proteins were similar to those in the HSR group after CQ + DEX administration. In summary, DEX induced autophagic activation in an HSR model. These findings suggest that DEX administration partially ameliorates HSR-induced lung injury via autophagic activation.

kn-abstract=Boron neutron capture therapy (BNCT) is a radiation therapy that selectively kills cancer cells at the cellular level using the boron neutron capture reaction (BNCR) (10B(n.α)7Li). The amount of boron 10B delivers in boronophenylalanine (BPA)-BNCT to achieve anti-tumor effects is ≈15–40 ppm. The same is true for all boron drugs; however, whether the same amount of 10B is required for other boron drugs with different accumulation characteristics has not been intensively investigated. Therefore, herein, a virtual cell model with intracellular organelles is prepared, and the BPA equivalent dose concentration to the cell nucleus is analyzed using particle and heavy ion transport code system-based microdosimetry. Additionally, the intranuclear minimal region (IMR) is set as a reference for the concept of the intranuclear domain in the microdosimetric kinetic model, and the BPA equivalent dose concentration to the IMR is estimated. The required boron delivery dose greatly varies depending on the dose assessment based on the accumulation characteristics of boron agents in intracellular organelles. Evaluation of the BNCR effect according to the accumulation characteristics without being influenced by the specified value of 15–40 ppm is recommended.
