Abstract
Background Drastic changes such as school closures and stay-at-home measures due to the global COVID-19 pandemic, may have long-term negative effects on children's mental health; however, longitudinal studies after 2021 are limited. This study aimed to observe the long-term effects of the COVID-19 pandemic on children's mental health by exploring changes in their mental health over a period of 18 months. Study design We conducted a longitudinal study at Chiba Prefecture in Japan, focusing on schoolchildren's mental health changes. Methods Data were obtained from the Strengths and Difficulties Questionnaire (SDQ) questionnaire conducted at single primary school three times from October 2021 to March 2023 which and included 183 participants. This study adopted a linear-mixed model to evaluate changes in children's SDQ scores, with sex and grade as the independent variables, and participants as a random effect. Results Regarding changes in SDQ scores, there were no significant changes in the total difficulty scores or in each subscale; Emotional Symptoms, Conduct Problems, Hyperactivity/Inattention, Peer Problems, and Prosocial Behavior. There was no statistically significant interaction between changes in SDQ scores and sex. Conclusions This report indicates that the impact of the COVID-19 pandemic on the mental health of Japanese primary schoolchildren was negligible in the later phase of the pandemic. However, the impact may differ from country to country owing to factors such as social restrictions during the COVID-19 pandemic.

Abstract
This study aimed to investigate adverse reactions to medications administered during palliative care and compare the responses of Board-Certified Pharmacists in Palliative Pharmacy (BCPPP) and non-BCPPP professionals. Methods: This multicentre prospective survey included hospital and community pharmacists who are members of the Japanese Society for Pharmaceutical Palliative Care and Sciences. Study participants included patients who experienced new drug reactions during the study period and responded to the requested survey items. The follow-up period for each eligible patient began on the day the pharmacists initiated the intervention and ended at discharge, death, or after one month of intervention. The primary endpoint was the impact of pharmacist intervention on adverse drug reactions. The pharmacists included in the study evaluated the severity of adverse drug reactions to assess the effect of their intervention using an integrated palliative care outcome scale before and after the intervention. Key findings: During the survey period, 79 adverse drug reaction intervention reports from 69 patients were obtained from 54 pharmacists (28 certified and 26 non-certified). The response rate was 1.62% (54/3,343). The management of palliative pharmacotherapy side effects by BCPPP and non-BCPPP significantly improved the patients' activities of daily living (P < 0.001). The BCPPP group intervened for significantly more patients with adverse drug reactions and overall adverse drug reactions than the non-BCPPP group (P < 0.023 and P < 0.013, respectively). Conclusion: BCPPP interventions can improve symptom management.

Abstract
1. This study assessed 1) the effects of Paracoccus carotinifaciens supplementation containing high astaxanthin levels on egg production performance and quality, 2) dynamics of carotenoids levels in the egg yolk and 3) taste of astaxanthin-rich egg yolk.2. Laying hens were fed diets containing different levels of P. carotinifaciens-derived astaxanthin (ASX; 0, 2, 4, 8, or 16 ppm) for 28 d (experiment 1) or a diet containing 16 ppm astaxanthin for 28 d followed by a 0 ppm astaxanthin diet for 28 days (experiment 2).3. Production performance, egg quality and egg yolk carotenoid levels were examined in experiment 1 (Ex1) and the dynamics of egg yolk carotenoid levels and egg yolk taste in experiment 2 (Ex2).4. ASX supplementation did not affect production performance or egg quality. ASX levels in the egg yolk became saturated after seven days of 16 ppm supplementation and decreased to less than one-tenth of the saturated levels seven days after supplementation cessation. Supplementation with 16 ppm ASX for 28 d did not affect egg yolk taste.5. Supplementation resulted in the production of ASX-rich eggs for a brief period without affecting production performance, egg quality or taste. Understanding the time taken for the incorporation of ASX into egg yolks is beneficial for value-added egg production and may help in minimising supplementation costs.

Abstract
BackgroundElevated serum IgG4 levels are one of the characteristic findings in immunoglobulin G4 (IgG4)-related disease (IgG4-RD). Serum IgG4 levels have an impact to a certain extent on the diagnosis of IgG4-RD although there are some issues in their sensitivity and specificity. In the reports from Japan, China, USA, and Europe, elevated serum IgG4 levels were reported to be observed in 83-97% of patients with IgG4-RD [1-5]. In the past investigations of hospital patients, some studies reported that 10-15% of hospital patients with elevated serum IgG4 levels had IgG4-RD [6,7]. However, in general adults with no symptom, investigations of prevalence of elevated serum IgG4 levels and/or IgG4-RD have rarely been conducted.ObjectivesThis study aimed to investigate the frequency of serum IgG4 elevation in the general Japanese population and its associated factors using data from resident examinations.MethodsWe measured the serum IgG4 levels in 1,204 residents who underwent a general medical examination in Ishikawa prefecture, Japan. Logistic regression analysis was used to search for factors related to elevated serum IgG4 levels. Secondary examinations were conducted for participants in whom elevation was identified.ResultsThe mean serum IgG4 level was 44 mg/dL, and elevated serum IgG4 levels were observed in 42 patients (3.5%). Univariate logistic regression analyses showed that male sex, older age, lower estimated glomerular filtration rates based on cystatin C (eGFR-CysC), serum high-density lipoprotein cholesterol levels, and higher hemoglobin A1c (HbA1c) levels were associated with elevated serum IgG4 levels. Subgroup analyses in men showed that older age, lower eGFR-CysC levels, and higher serum HbA1c levels were associated with elevated serum IgG4 levels. In contrast, the analyses in women found no significant factors. One of the 10 residents who underwent secondary examinations was diagnosed with possible IgG4-related retroperitoneal fibrosis.ConclusionIn the general population, elevated serum IgG4 levels are more common in elderly men, which is similar to the epidemiological features of IgG4-RD.References[1]Inoue D, et al.

Abstract
Axon pruning facilitates the removal of ectopic and misguided axons and plays an important role in neural circuit formation during brain development. Sema3F and its receptor neuropilin-2 (Nrp2) have been shown to be involved in the stereotyped pruning of the infrapyramidal bundle (IPB) of mossy fibers of the dentate gyrus (DG) in the developing hippocampus. Collapsin response mediator proteins (CRMPs) were originally identified as an intracellular mediator of semaphorin signaling, and the defective pruning of IPB was recently reported in CRMP2-/- and CRMP3-/- mice. CRMP1 and CRMP4 have high homology to CRMP2 and CRMP3, and their expression in the developing mouse brain overlaps; however, their role in IPB pruning has not yet been examined. In this study, we report that CRMP4, but not CRMP1, is involved in IPB pruning during neural circuit formation in the hippocampus. Our genetic interaction analyses indicated that CRMP2 and CRMP4 have distinct functions and that CRMP2 mediates IPB pruning via Nrp2. We also observed the altered synaptic terminals of mossy fibers in CRMP2 and CRMP4 mutant mice. These results suggest that CRMP family members have a distinct function in the axon pruning and targeting of mossy fibers of the hippocampal DG in the developing mouse brain.

Abstract
Abstract
Background
Elder abuse is a serious public health concern that increases the risks of negative health outcomes globally. It is well known that abuse in older adults is associated with depression; however, longitudinal studies investigating the causal relationship between these events are scarce. Because the cause precedes the result over time, the temporal relationships between abuse and depression should be verified from each direction. This longitudinal study therefore investigated and clarified whether depression causes or results from elder abuse among older Japanese adults.
Methods
Two longitudinal analyses were conducted using data derived from the Japan Gerontological Evaluation Study. The data were collected in 2010 and 2013 through a mail survey of 1737 people (983 females, 754 males) across Japan.
Results
Of those who did not experience abuse in 2010, 38 (5.0%) males and 53 (5.4%) females newly experienced abuse in 2013. Among respondents who did not have depressive symptoms in 2010, 60 (8.0%) males and 61 (6.2%) females newly reported depressive symptoms in 2013. After adjusting for demographic factors in analysis 1, people who experienced abuse were 2.28-fold (95% confidence interval [CI] = 1.68-3.09) more likely to have depressive symptoms 3 years later than those who were not abused. In analysis 2, respondents who had mild or severe depression in 2010 were 2.23-fold (95% CI = 1.61-3.10) more likely to have experienced abuse after 3 years than those who did not have depression.
Conclusions
After adjusting for several demographic factors, the results showed that abuse can lead to depression and that depression can be a cause of abuse. Therefore, preventing abuse should be considered from both directions.
Key messages
Elder abuse could be a cause for depressive symptoms. Depressive symptoms could be a cause of elder abuse.

Abstract
The first description of well-preserved fur of one male and one female cubs of the fossil cave lion Panthera spelaea (finds of 2017-2018, Semyuelyakh River, Yakutia, Russia) is presented in comparison with the fur of two cubs (a male and a female) of the extant African lion P. leo and adult lions of both species: the color, differentiation, configuration, microstructure, and internal design of hair of different categories are considered. The coat of the cave lion is similar but not identical to that of the African lion, because it contains a high thick undercoat of spiral-shaped thick and airy down hair. This difference is most pronounced in the cave lion cubs, in which, however, the fur is not differentiated to the same extent as in the adult. The microstructure of hair is species-specific and subject to intraspecific age-related variability. Adaptive features of the hair structure in the cave lion are noted.

Abstract
The current research work deals with the preparation of TiO2 and GO/TiO2 composite by simple, chemical, cost effective hydrothermal method. Graphene oxide (GO) is prepared by modified Hummer's method. Dispersion of GO is achieved by an ultrasonic cleaning bath for 1 h. using a power of 200 W and at a frequency of 40 kHz. The prepared catalyst material is characterized by different characterization techniques. XRD study confirms the prepared material is polycrystalline in nature. The synthesized TiO2 and GO/TiO2 photocatalyst materials are used to study the photocatalytic degradation of salicylic acid under sunlight illumination. GO/TiO2 composite shows superior photocatalytic activity than TiO2. GO/TiO2 composite shows 57% degradation of salicylic acid. Mineralization of salicylic acid is studied using chemical oxygen demand.

Abstract
Abstract
Background
It has been thought BNP is induced by undetermined stretch-activated receptors, however, which receptor is associated remains unknown. The stretch-activated receptors include mechanically gated channels, which can be activated by a mechanical stimulus alone, and mechanically modulated channels, which require nonmechanical stimuli such as agonists. It has been recently shown that 1.1kb segment of mouse NPPB promoter dose not reproduce the pattern of reactivation of BNP in adult heart, although it could monitor the expression of BNP in neonatal cardiomyocytes.
Purpose
Our aim is to develop a true BNP reporter mouse and examine whether this mouse is useful or not for the investigation of BNP reactivation mechanism in adult heart and for the measurement of serum-induced BNP expression in patients with heart failure.
Methods
We generated the BNP reporter mice by knocking luciferase cDNA in the initiation site of NPPB. In vivo imaging of luciferase was performed in the BNP reporter mice after the intraperitoneal injection of luciferin. The luciferase activity was examined in neonatal cardiomyocyte, isolated adult cardiomyocytes, adult cardiac dissected tissue with or without 120–150% stretch or angiotensin II stimulation. Left anterior descending (LAD) coronary artery was ligated to study myocardial infarction. Cardiac dissected tissue segments from the BNP reporter mouse were incubated for 8 hours with 20% serum from patients with or without heart failure and the luciferase activity was measured after homogenization.
Results
The in vivo imaging system showed the activity of BNP was high in 1 day-old neonates and the reactivation of BNP in the adult heart after LAD ligation could be monitored by the luciferase activity (figure). The treatment of Ang II could increase the activity of pBNP more than ten folds in heart tissue from adult mice. On the other hand, the 120–150% stretch did not show any effect on the activity of pBNP in this system. We could not observe any activation of pBNP in cultured neonatal or adult cardiomyocytes demonstrated by immunostain with antibodies against luciferase after 120–150% stretch. Interestingly, the luciferase activity was extensively higher in cultured heart tissue segments from the BNP reporter mice after the treatment of serum from patients with heart failure than without heart failure.
In vivo imaging of BNP reporter mice
Conclusion
These results indicate the BNP reporter mouse by knock-in technology is useful for the analysis of mechanism in reactivation of BNP in adult heart and the elevation of BNP in patients of heart failure partly due to the serum-derived induction of BNP from heart.

Abstract
AIMS Colectomy is the current approach for patients with endoscopically unresectable benign polyps but risks considerable morbidity. Full-thickness laparoendoscopic excision (FLEX) is a novel procedure, specifically developed to treat endoscopically unresectable benign colonic polyps, which could reduce the treatment burden of the current approach and improve outcomes. However, traditional evaluations of surgical innovations lack methodological rigour. This study reports the development and feasibility of the FLEX procedure in selected patients. METHOD A prospective development study using the Idea, Development, Evaluation, Assessment, Long-term study (IDEAL) framework was undertaken, by one surgeon, of the FLEX procedure in selected patients with endoscopically unresectable benign colonic polyps. Three-dimensional (3D)-CT colonography reconstructions were used preoperatively to rehearse patient-specific, critical manoeuvres. Targetted, full-thickness excision was performed: after marking the margin of the caecal polyp using circumferential endoscopic argon plasma coagulation, transmural endoscopic sutures were used to evert the bowel and resection was undertaken by laparoscopic linear stapling. Feasibility outcomes (establishing 'local success') included evidence of complete polyp resection without adverse events (especially safe closure of the excision site). RESULTS Ten patients [median (interquartile range) age: 74 (59-78) years] with polyp median diameters of 35 (30-41) mm, were referred for and consented to receive the FLEX procedure. During the same time frame, no patient underwent colectomy for benign polyps. One further patient received FLEX for local excision of a presumed malignant polyp because severe comorbidity prohibited standard procedures. The FLEX procedure was successfully performed locally, with complete resection of the polyp and safe closure of the excision site, in eight patients. Three noncompleted procedures were converted to laparoscopic segmental colectomy under the same anaesthetic because of endoscopic inaccessibility (two patients) and transcolonic suture failure (one patient). CONCLUSIONS The FLEX procedure is still under development. Early data demonstrate that it is safe for excision of selected benign polyps. Modifications to transcolonic suture delivery are now required and there is a need for wider adoption before more definitive evaluation can be performed.

Abstract
BACKGROUND AND PURPOSE Tapering immunosuppressants is desirable in patients with well-controlled myasthenia gravis (MG). However, the association between tapering of calcineurin inhibitor dosage and reduction-associated exacerbation is not known. The aim of this study was to clarify the frequency of reduction-associated exacerbation when tacrolimus is tapered in stable patients with anti-acetylcholine receptor antibody-positive MG, and to determine the factors that predict exacerbations. METHODS We retrospectively analyzed 115 patients in whom tacrolimus dosage was tapered. The reduction-associated exacerbation was defined as the appearance or worsening of one or more MG symptoms <3 months after the reduction. RESULTS Tacrolimus dosage was successfully tapered in 110 patients (96%) without any exacerbation. Five patients (4%) experienced an exacerbation, but symptoms were reversed in all patients when the tacrolimus dose was increased to the previous maintenance level. No patient developed an MG crisis. The age at onset was significantly earlier (30 vs. 56 years, P = 0.025) and the reduction in dosage was significantly larger (2.0 vs. 1.0 mg/day, P = 0.002) in patients with reduction-associated exacerbation than in those without exacerbation. The cut-off values determined in a receiver-operating characteristic curve analysis were 52 years (sensitivity, 57%; specificity, 100%) for the age at onset and 1.5 mg (sensitivity, 80%; specificity, 100%) for the dose reduction. CONCLUSION Tapering of tacrolimus was possible in most patients with well-controlled anti-acetylcholine receptor antibody-positive MG. Early age at onset and a large reduction from maintenance dosage were associated with exacerbation. Reductions ≤1.5 mg/day from the maintenance dosage should be considered for patients with late-onset disease.

Abstract
Ingestion of Bacillus subtilis C-3102 spores (C-3102) has relieved the symptoms of diarrhoea in piglets and changed the composition of gut microbiota in humans. Recently, it was suggested that the composition of the human gut microbiota affects stool consistency. In this study, a double-blind, randomised, placebo-controlled trial was conducted to assess the preventive effects of chronic diarrhoea in healthy volunteers with loose stools by ingestion of C-3102. The results showed that oral doses of C-3102 tablets significantly decreased the Bristol Stool Scale score and stool frequency, and also significantly improved abdominal sounds. With regard to gut microbiota, the relative abundance of Lachnospira, Actinomyces and SMB53 were significantly changed. This study shows that C-3102 could be effective for treating loose stools (Trial registration: UMIN000022583, http://tinyurl.com/ya4refqn ).

Abstract
BACKGROUND Digital photogrammetry provides measurements of body angles or distances which allow for quantitative posture assessment with or without the use of external markers. It is becoming an increasingly popular tool for the assessment of the musculoskeletal system. The aim of this paper is to present a structured method for the analysis of posture and its changes using a standardized digital photography technique. MATERIAL AND METHODS The purpose of the study was twofold. The first one comprised 91 children (44 girls and 47 boys) aged 7-10 (8.2 ± 1.0), i.e., students of primary school, and its aim was to develop the photographic method, choose the quantitative parameters, and determine the intraobserver reliability (repeatability) along with the interobserver reliability (reproducibility) measurements in sagittal plane using digital photography, as well as to compare the Rippstein plurimeter and digital photography measurements. The second one involved 7782 children (3804 girls, 3978 boys) aged 7-10 (8.4 ± 0.5), who underwent digital photography postural screening. The methods consisted in measuring and calculating selected parameters, establishing the normal ranges of photographic parameters, presenting percentile charts, as well as noticing common pitfalls and possible sources of errors in digital photography. RESULTS A standardized procedure for the photographic evaluation of child body posture was presented. The photographic measurements revealed very good intra- and inter-rater reliability regarding the five sagittal parameters and good reliability performed against Rippstein plurimeter measurements. The parameters displayed insignificant variability over time. Normative data were calculated based on photographic assessment, while the percentile charts were provided to serve as reference values. The technical errors observed during photogrammetry are carefully discussed in this article. CONCLUSIONS Technical developments are allowed for the regular use of digital photogrammetry in body posture assessment. Specific child positioning (described above) enables us to avoid incidentally modified posture. Image registration is simple, quick, harmless, and cost-effective. The semi-automatic image analysis, together with the normal values and percentile charts, makes the technique reliable in terms of child's posture documentation and corrective therapy effects' monitoring.

Abstract
The chemical parameters and the functionalities of six monofloral honeys of different botanical and geographical origins were investigated. Vitamins B1, B2, and C and the protein content of majority of honeys were distinguishable from general honey. Honeys not only were rich in a variety of functional components like flavonoids but also had strong anti-oxidant activities, scavenging activities against ROS, and anti-hypertensive and anti-allergic activities. Honeys were heated at 100 °C for 24 h and their browning intensity during heating process was observed to vary with botanical origin. The functional properties of caramelization and maillard reaction (MR) products derived from honeys during heating were evaluated. The browning of honeys progressed regardless of honey species. Anti-oxidant activities and scavenging activities against superoxide and DPPH radicals of products drastically increased, but ACE and hyaluronidase activities gradually decreased with passage of heating time. It concluded that the products, mainly melanoidins, produced simultaneously to browning process in caramelization and MR contributed to the expression of its useful function.

Abstract
Introduction The frequency of telephone advice for cardiopulmonary resuscitation (T-CPR) and its effect are unclear. We have few data concerning how many persons who are willing to perform CPR under the setting of the T-CPR system. Most of these data were from action reports in the pre-hospital EMS records. Methods: This study was a population-based observational case series of out-of-hospital cardiopulmonary arrest (OHCPA). The primary outcome was the acceptability of a bystander to perform CPR according to T-CPR. In our emergency department, one medical doctor interviewed the bystanders regarding T-CPR and CPR; this doctor was devoted to obtaining information from the patients. Results Of the 803 patients in, T-CPR advice was provided in 47% and CPR was actually performed in 47% independent of T-CPR guidance. Of the 373 cases in which lay persons received T-CPR, 95% provided CPR. Dispatchers could more easily provide T-CPR to family members compared with friends and passengers. Twenty-one percent of callers made emergency calls after consulting with others (indirect call). In non-traumatic victims who underwent bystander CPR, 43% experienced the return of spontaneous circulation, and 5% were discharged with a mild disorder or no neurological abnormality. Conclusions We conclude that 95% of bystanders are willing to perform CPR under the T-CPR system, but we cannot conclude that bystander CPR may not affect the survival rate. These findings indicate that bystanders should be guided with T-CPR. (Hong Kong j.emerg. med. 2016;23:220-226)

Abstract
A new compact low-temperature hydrogen ion beam apparatus has been developed for in situ physical property measurements. Introduction of hydrogen can significantly alter the physical properties of materials. Conventional methods such as exposure to H2 gas are limited to materials having hydrogen sorption. The present method is, in principle, applicable to any material of interest. Our setup provides a facile way to conduct both low-temperature hydrogen ion beam irradiation and in situ electrical resistivity measurements, which enables observation of novel physical properties induced by the low-temperature irradiation. The lowest temperature of 3.8 K was achieved by utilizing a newly designed rotatable radiation shield and a closed-cycle cryostat, which is advantageous for long-time low-temperature experiments for heavy hydrogen doping and in situ analysis. It was found that the resistivity of ZnO largely decreased by hydrogen ion beam irradiation at 50 K. Furthermore, the in situ measurements revealed an unforeseen irreversible thermal hysteresis for resistivity.

Abstract
BACKGROUND Previous attempts at sentinel lymph node (SLN) mapping in colon cancer have been compromised by ineffective tracers and the inclusion of advanced disease. This study evaluated the feasibility of fluorescence detection of SLNs with indocyanine green (ICG) for lymphatic mapping in T1/T2 clinically staged colonic malignancy. METHODS Consecutive patients with clinical T1/T2 stage colon cancer underwent endoscopic peritumoral submucosal injection of indocyanine green (ICG) for fluorescence detection of SLN using a near-infrared (NIR) camera. All patients underwent laparoscopic complete mesocolic excision surgery. Detection rate and sensitivity of the NIR-ICG technique were the study endpoints. RESULTS Thirty patients mean age = 68 years [range = 38-80], mean BMI = 26.2 (IQR = 24.7-28.6) were studied. Mesocolic sentinel nodes (median = 3/patient) were detected by fluorescence within the standard resection field in 27/30 patients. Overall, ten patients had lymph node metastases, with one of these patients having a failed SLN procedure. Of the 27 patients with completed SLN mapping, nine patients had histologically positive lymph nodes containing malignancy. 3/9 had positive SLNs with 6 false negatives. In five of these false negative patients, tumours were larger than 35 mm with four also being T3/T4. CONCLUSION ICG mapping with NIR fluorescence allowed mesenteric detection of SLNs in clinical T1/T2 stage colonic cancer. CLINICALTRIALS.GOV: ID: NCT01662752.

Abstract
E26 transformation-specific (Ets) family transcription factors are known to play roles in various biological phenomena, including immunity, in vertebrates. However, the mechanisms by which Ets proteins contribute to immunity in invertebrates remain poorly understood. In this study, we identified a cDNA encoding BmEts2, which is a putative orthologue of Drosophila Yan and human translocation-ets-leukemia/Ets-variant gene 6, from the silkworm Bombyx mori. Expression of the BmEts2 gene was significantly increased in the fat bodies of silkworm larvae in response to injection with Escherichia coli and Staphylococcus aureus. BmEts2 overexpression dramatically repressed B. mori Rels (BmRels)-mediated promoter activation of antimicrobial peptide genes in silkworm cells. Conversely, gene knockdown of BmEts2 significantly enhanced BmRels activity. In addition, two κB sites located on the 5' upstream region of cecropin B1 were found to be involved in the repression of BmRels-mediated promoter activation. Protein-competition analysis further demonstrated that BmEts2 competitively inhibited binding of BmRels to κB sites. Overall, BmEts2 acts as a repressor of BmRels-mediated transactivation of antimicrobial protein genes by inhibiting the binding of BmRels to κB sites.

Abstract
Enzymatic hydrolysates were prepared from commercially available kamaboko type samples using three gastrointestinal proteases and protein proteases. The yields of these hydrolysates were about 10–31% and these protein contents ranged from 62 to 533 g/mg per sample powder on their wet weight basis. The hydrolysates showed higher antioxidative activities and scavenging activities against active oxygen species such as hydroxyl radical and superoxide anion radical. Moreover, these hydrolysates exhibited high angiotensin I-converting enzyme inhibitory activites that were similar or higher than those from various fermented foods such as fish sauce, sake, soy sauce, vinegar, miso and natto. The antioxidative and antihypertensive activities of commercially available kamaboko type samples were not related to the colour of the samples. The results indicated that enzymatic hydrolysates from commercially available kamaboko type samples, whose health benefits are scientifically supported, have the potential to be an increasingly important component of a healthy lifestyle and to be beneficial to the public and the food industry.
