Abstract
BACKGROUND Triple-negative breast cancer (TNBC) is the most heterogeneous breast cancer subtype. Partly due to its heterogeneity, it is currently challenging to stratify TNBC patients and predict treatment outcomes. METHODS In this study, we examined blood cytokine profiles of TNBC patients throughout treatments (pre-treatment, during chemotherapy, pre-surgery, and 1 year after the surgery in a total of 294 samples). We analyzed the obtained cytokine datasets using weighted correlation network analyses, protein-protein interaction analyses, and logistic regression analyses. RESULTS We identified five cytokines that correlate with good clinical outcomes: interleukin (IL)-1α, TNF-related apoptosis-inducing ligand (TRAIL), Stem Cell Factor (SCF), Chemokine ligand 5 (CCL5 also known as RANTES), and IL-16. The expression of these cytokines was decreased during chemotherapy and then restored after the treatment. Importantly, patients with good clinical outcomes had constitutively high expression of these cytokines during treatments. Protein-protein interaction analyses implicated that these five cytokines promote an immune response. Logistic regression analyses revealed that IL-1α and TRAIL expression levels at pre-treatment could predict treatment outcomes in our cohort. CONCLUSION We concluded that time-series cytokine profiles in breast cancer patients may be useful for understanding immune cell activity during treatment and for predicting treatment outcomes, supporting precision medicine. TRIAL REGISTRATION The study has been registered with the University Hospital Medical Information Network Clinical Trials Registry ( http://www.umin.ac.jp/ctr/index-j.htm ) with the unique trial number UMIN000023162. The association Japan Breast Cancer Research Group trial number is JBCRG-22. The clinical outcome of the JBCRG-22 study was published in Breast Cancer Research and Treatment on 25 March 2021. https://doi.org/10.1007/s10549-021-06184-w .

Abstract
Wickerhamiella is a genus of budding yeast that is mainly isolated from environmental samples, and 40 species have been detected. The yeast isolated from human clinical samples usually only contain three species: W. infanticola, W. pararugosa and W. sorbophila. In this study, we isolated W. tropicalis from a blood sample of a six-year-old female with a history of B-cell precursor lymphoblastic leukemia in Japan in 2022. Though the strain was morphologically identified as Candida species by routine microbiological examinations, it was subsequently identified as W. tropicalis by sequencing the internal transcribed spacer (ITS) of ribosomal DNA (rDNA). The isolate had amino acid substitutions in ERG11 and FKS1 associated with azole and echinocandin resistance, respectively, in Candida species and showed intermediate-resistant to fluconazole and micafungin. The patient was successfully treated with micafungin. Furthermore, matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) detected three novel peaks that are specific for W. tropicalis, indicating that MALDI-MS analysis is useful for rapid detection of Wickerhamiella species in routine microbiological examinations.

Abstract
Purpose Whether the coronavirus disease 2019 (COVID-19) pandemic had any effect on the time between blood culture collection and administration of antibiotics in the outpatient Department of Emergency Medicine in a single university hospital in Japan was investigated, and the intervention carried out by the antimicrobial stewardship team (AST) to promote the appropriate use of antibiotics was examined. Patients and Methods The monthly percentage of patients who visited the outpatient Department of Emergency Medicine between January 2019 and December 2021 and received an intravenous antibiotic within 3 hours of blood culture collection was calculated. The AST calculated a quality indicator (QI) based on the results of the investigation and started QI monitoring and hospital feedback. Results From January 2020 to March 2021 (the third COVID-19 wave), the implementation rate of antibiotic administration within 3 hours after blood culture collection decreased as the COVID-19 pandemic spread, and the implementation rate tended to increase as the number of COVID-19-positive patients decreased. However, when the AST started monitoring and feedback from April 2021, although there was a temporary decline in the early stages of the fifth wave when the scale of infection was large, the implementation rate rose and was maintained by AST intervention. (the fourth and the fifth COVID-19 waves) (P<0.01). Also, the implementation rate was significantly lower during the COVID-19 pandemic than during the non- pandemic (P<0.05). Conclusion The early COVID-19 pandemic may have affected the delay in time from blood culture collection to antibiotic administration. Later, in recurring COVID-19 pandemics, AST intervention eliminated this problem. When a bacterial infection such as sepsis is suspected, delayed treatment can be prevented by promptly collecting a blood culture, irrespective of concerns about COVID-19 infection. Calculating the QI may promote AST activities and the appropriate use of antibiotics.

Abstract
A 38-year-old female with systemic lupus erythematosus (SLE) initiated belimumab treatment. One month later, she presented with a reddish painful swelling on her right lower leg. She was treated with ceftriaxone and vancomycin. However, novel erythematous papules and indurated nodules appeared on both her lower legs. Skin biopsy revealed microabscess formation with mixed cell granuloma surrounded by inflammatory cell infiltration within the dermis with subcutaneous fat tissue. A large number of acid-fast bacilli were observed with Ziehl-Neelsen staining. DNA sequencing of both the hsp65 and the 16S rRNA sequences showed a 100% match with the corresponding region of Mycobacterium haemophilum. Mycobacterial culture revealed satellite growth enhancement on Middlebrook 7H11 agar plates around a paper strip containing hemin. She was treated with levofloxacin, rifabutin, and ethambutol. Within 13 months, her cutaneous lesions improved markedly without any side effects. The B cell-targeted biologic belimumab, a fully humanized IgG1γ monoclonal antibody that inactivates B lymphocyte stimulator, has been considered to be beneficial for active SLE. However, this therapy could increase the risk for the development of biologic therapy-associated mycobacterial infections, both tuberculosis and nontuberculous mycobacteria infections.

Abstract
Abstract
Background: Abemaciclib is a selective CDK4 and CDK6 inhibitor with demonstrated efficacy in hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer. The most common adverse event across previous trials was early-onset diarrhea, affecting the patients’ quality of life and necessitating dose reductions. However, the exact mechanism for the lower rate of diarrhea in the other CDK4 and CDK6 inhibitors compared with abemaciclib is unknown. Ample evidence indicates that the gut microbiome is a tumor-extrinsic factor associated with the anti-tumor response; however, reported microbial signatures associated with adverse events by anti-cancer agent are inconsistent. To determine the underlying mechanism, we evaluated the correlation between diarrhea with abemaciclib and microbiota signatures in a metastatic breast cancer cohort.
Methods: The KBCRN-A002 study is a multicenter, prospective cohort study, which aims to evaluate the association between gut microbiota signatures and abemaciclib-induced diarrhea in breast cancer patients. Patients with metastatic breast cancer who were receiving abemaciclib were eligible. The primary objective of this study is the correlation between diarrhea and the microbiota signatures and immune profile. Incidence and severity of diarrhea were evaluated by the Bristol stool scale at baseline, from day 1 to day 14, and at day 90 of treatment. Stool samples were collected at baseline and at day 90 after the start of abemaciclib treatment. The gut microbiota signature was evaluated by 16S rRNA analysis. Blood samples were collected at baseline and at days 14 and 90 after starting abemaciclib to evaluate the correlation between the gut microbiota signatures and the systemic immune profile in peripheral blood mononuclear cells (PBMCs). The immune profile was evaluated by mass cytometry, multi-plex cytokines assay, and RNA-sequencing of bulk PBMCs. We characterized the gut microbiota signatures, immune cell composition, immune cell signature, comprehensive cytokines, and severity of diarrhea in all patients.
Results: We analyzed 39 patients, 77 stool samples, and 117 blood samples. In the preplanned interim analysis, among the 39 patients, 90% experienced diarrhea. Depleted gut microbiome α-diversity was positively associated with abemaciclib treatment and the severity of diarrhea. The relative abundances of 10 intestinal bacteria species increased and those of 18 intestinal bacteria decreased significantly after abemaciclib treatment, including bacteria known to be involved in diarrhea severity and anti-tumor immunity, such as Faecalibacterium (Table). The immune cell and cytokine profiles in PBMCs were also associated with the gut microbiota signatures.
Conclusions: Gut microbiota signatures are associated with abemaciclib-induced diarrhea and the immune profile in metastatic breast cancer patients. These findings can help to elucidate the mechanism of diarrhea caused by abemaciclib and offer strategies for its management and prevention.

Abstract
Abstract
Background: Stable humanized immune mice transplanted with peripheral blood mononuclear cells (PBMCs) derived from breast cancer patients are important models for assessing the tumor immune responses and the tumor immune microenvironment in breast cancer, helping to advance both pre-clinical and clinical research. The PBMCs of breast cancer patients exhibit various differences from those of healthy individuals depending on the stage of cancer progression, subtype, and type of treatment. Recent studies indicate an association of the self-renewal signatures of T cells with successful generation of a humanized mouse model; however, the optimal T cell signature for the successful generation of a humanized mouse model derived from cancer patient cells is poorly understood. Therefore, we examined the relationship between the signature of T cell subsets, focusing on the self-renewal signatures, in PBMCs derived from patients with breast cancer and the successful generation of a humanized immune mouse model. Materials and Methods: We collected PBMCs from 12 patients with breast cancer. All samples were stimulated with interleukin-2 and beads coated with CD3 and CD28 agonist antibodies to expand T cells. After washing, 1 × 10^7 cells/mouse were intraperitoneally injected into NOD/Shi-scid IL2rgamma (null) (NOG) mice. Transplants were performed on three mice per case. Successful engraftment of immune cells into NOG mice was defined by the presence of human CD45+ cells in one or more mice. Self-renewal signatures of in vitro expanded T cells before injection into NOG mice, including the markers T cell factor-1 (TCF-1), CD45RA, CCR7, CD95, and CXCR3, were determined using flow cytometry, mass cytometry and quantitative RT-PCR. Comparisons between groups of data were evaluated by t-test. Results: The success rate of engraftment of immune cells derived from breast cancer patients into NOG mice was 66.7% (8 out of 12 patients). After expansion, the magnitude of the CD8+ stem cell memory subset and the TCF-1 expression level on the CD4+ and CD8+ T cells in the engrafted group were significantly higher than those in non-engrafted group. TCF-1 and CCR7 mRNA levels in the engrafted group were upregulated compared with those in non-engrafted group. The success of engraftment was not associated with clinical characteristics such as breast cancer progression, subtype, or prior chemotherapy treatment. Conclusion: The self-renewal signatures of T cells from breast cancer patients were associated with successful engraftment of a humanized mouse model. These results suggest that prior identification of the self-renewal signatures of the T-cell population is of direct relevance to the appropriate design of a pre-clinical model for testing immunotherapies and for elucidating the characteristics of the tumor immune microenvironment.

Abstract
OBJECTIVE This study was undertaken to evaluate the effects of red wine from grapes oligomeric procyanidins (OPCs) intake on skin color and skin moisture in Japanese healthy women. The purpose of this study was to improve skin condition, with the primary endpoint set to improve sunburn by ultraviolet (UV) and the secondary endpoint set to improve dryness. PATIENTS AND METHODS A randomized, placebo-controlled, double-blind, parallel-group study was conducted on 100 subjects (30 to 59 years of age). They were administered a test beverage, including 200 mg of the red wine OPCs (the test beverage group) or a placebo beverage (the control beverage group) once a day for 12 weeks. The properties of facial skin were measured at 0 (start value), 4th, 8th, and 12th week of the test period. RESULTS After 12 weeks of administration, the pigmentation scores and melanin index values of the OPC group were significantly reduced from the start value and were lower than the control group (p<0.05). In addition, the OPC group showed a significant increase in water content of the stratum corneum compared to the start value, while that of the control group significantly decreased. CONCLUSIONS The red wine OPCs showed the effects of skin whitening and moisturizing, and it is suggested that OPCs may improve the skin condition of healthy women.

Abstract
AIMS Otitis externa (OE), one of the most common ear diseases in dogs, is caused by bacterial pathogens such as Staphylococcus sp. To understand the network of microbial communities in the canine ear canal affected with OE, we performed a cross-sectional study using next-generation sequencing. METHODS AND RESULTS Ear swab samples were collected from 23 OE-affected and 10 healthy control dogs, and the 16S rRNA gene sequenced using Illumina MiSeq. The otic microbiota in the OE-affected dogs showed significantly decreased alpha diversity compared to controls. The community composition also differed in the affected group, with significantly higher relative abundance of the phylum Firmicutes and the genus Staphylococcus (P = 0·01 and 0·04 respectively). Contrary to our expectations, the severity of the disease did not impact the otic microbiota in OE-affected dogs. CONCLUSIONS The ear canal microbiota of OE-affected dogs is distinct from that of healthy dogs, irrespective of disease status. SIGNIFICANCE AND IMPACT OF THE STUDY This study, one of the few detailed analyses of the otic microbiota, can provide practical information for the appropriate treatment of canine OE.

Abstract
Incidental gallbladder carcinoma (IGC), defined as unexpected malignancy identified in the surgical gallbladder specimen of a cholecystectomy performed for a benign diagnosis, can be difficult to suspect preoperatively. Furthermore, there are valid clinical reasons to defer reoperation for additional resection, particularly in elderly patients. The present study aimed to determine the long-term outcomes and prognostic factors associated with recurrence in patients with IGC. The medical records of 678 patients who underwent cholecystectomy at Toyooka Hospital between September 2011 and November 2017 were reviewed. The cases identified to be IGC were retrospectively analyzed to determine patient and histopathological characteristics, surgical details, long-term outcomes and factors associated with cancer recurrence. A total of 22 patients were diagnosed with gallbladder carcinoma following cholecystectomy by histopathological examination, and 12 of these were identified to be IGC. The median age was 80 years (range 70-89 years). Although 6 of the 12 patients with IGC had stage pT2 or pT3 tumors, only 1 patient underwent additional resection. Recurrence occurred in 3 of the 8 patients who did not undergo additional resection and were available for long-term follow-up. Recurrence was not associated with the extent of tumor invasion but may be associated with other histopathological findings, preoperative treatment history and risk factors for recurrence. Furthermore, long-term survival was observed in patients with pT2 and pT3 tumors who did not undergo additional resection. Recurrence was not associated with the extent of tumor invasion but may be associated with other histopathological findings, preoperative treatment history, and risk factors for recurrence. Furthermore, long-term survival was observed in patients with pT2 and pT3 tumors who did not undergo additional resection. Even if it is a progressive IGC case, appropriate preoperative treatment or cholecystectomy without persistence of the carcinoma cell, based on a preoperative image evaluation and a postoperative histopathological examination, may greatly influence the long-term prognosis of IGC.

Abstract
PURPOSE Elastase, produced by Aspergillus fumigatus and A. flavus, is an important pathogenic factor in pulmonary aspergillosis. We investigated the possibility of using A. fumigatus-derived A. fumigatus elastase inhibitor (AFUEI) as a therapeutic agent. As native-AFUEI (N-AFUEI) has an extremely low yield, we generated a synthetic-AFUEI (S-AFUEI) and investigated whether S-AFUEI has a biological activity against A. fumigatus elastase (AFUE) and inhibits cytotoxicity. METHODOLOGY A. fumigatus was cultured in Yeast Carbon Base (YCB) -elastin culture medium for 3-7 days, and AFUE was purified by chromatography using DE52 cellulose and Sephadex G-75 column. Elastolytic activity was examined using Glt-Ala-Ala-Pro-Leu-pNA (GAAPLNA) as the substrate. The hydrolytic activity of AFUE was determined using the characteristic substrates, fibrinogen and collagen (Type IV), and human cell cytotoxicity was measured colorimetrically. Furthermore, the inhibitory effect of S-AFUEI on these activities was examined. RESULTS We confirmed that S-AFUEI demonstrated elastase inhibitory activity and heat stability equivalent to that demonstrated by N-AFUEI, and inhibited human collagen hydrolytic activity and human fibrinogen hydrolytic activity. Further, S-AFUEI inhibited cytotoxicity in AFUE human pulmonary artery endothelial cells (HPAEC), human small airway epithelial cells (HSAEC), and human pulmonary alveolar epithelial cells (HPAEpiC). CONCLUSION As S-AFUEI strongly inhibited cytotoxicity induced by elastase in human-derived cells, it could prove beneficial for the treatment of pulmonary aspergillosis.

Abstract
Background Recently, evaluation of quality of life (QOL) has been recognized as a significant outcome measure in the treatment of several cancers. In this study, the Anti-Cancer Drugs-Breast (ACD-B) QOL score was used to assess disease-specific survival in women with breast cancer undergoing preoperative chemotherapy (POC). Methods QOL-ACD-B scores were evaluated before and after POC. The cut-off value of QOL-ACD-B contributing to events such as relapse or death was calculated by receiver operating characteristic (ROC) curve analysis. Results In 300 women with breast cancer treated with POC, QOL was significantly reduced (P < 0·001). A high QOL-ACD-B score before POC was an independent factor in the multivariable analysis of overall survival (hazard ratio 0·26, 95 per cent c.i. 0·04 to 0·96). Conclusion Evaluation by QOL-ACD-B before POC may be useful to predict the prognosis of patients with breast cancer undergoing POC.

Abstract
In developing teeth, the sequential and reciprocal interactions between epithelial and mesenchymal tissues promote stem/progenitor cell differentiation. However, the origin of the stem/progenitor cells has been the subject of considerable debate. According to recent studies, mesenchymal stem cells originate from periarterial cells and are regulated by neurons in various organs. The present study examined the role of innervation in tooth development and rodent incisor stem/progenitor cell homeostasis. Rodent incisors continuously grow throughout their lives, and the lower incisors are innervated by the inferior alveolar nerve (IAN). In this study, we resected the IAN in adult rats, and the intact contralateral side served as a nonsurgical control. Sham control rats received the same treatment as the resected rats, except for the resection process. The extent of incisor eruption was measured, and both mesenchymal and epithelial stem/progenitor cells were visualized and compared between the IAN-resected and sham-operated groups. One week after surgery, the IAN-resected incisors exhibited a chalky consistency, and the eruption rate was decreased. Micro–computed tomography and histological analyses performed 4 wk after surgery revealed osteodentin formation, disorganized ameloblast layers, and reduced enamel thickness in the IAN-resected incisors. Immunohistochemical analysis revealed a reduction in the CD90- and LRIG1-positive mesenchymal cell ratio in the IAN-resected incisors. However, the p40-positive epithelial stem/progenitor cell ratio was comparable between the 2 groups. Thus, mesenchymal stem/progenitor cell homeostasis is more related to IAN innervation than to epithelial stem/progenitor cells. Furthermore, sensory nerve innervation influences subsequent incisor growth and formation.

Abstract
Abstract:In this study we have attempted to classify the acceleration signal, while walking both at horizontal level, and upstairs and downstairs, using wavelet analysis. The acceleration signal close to the body’s center of gravity was measured while the subjects walked in a corridor and up and down a stairway. The data for four steps were analyzed and the Daubecies 3 wavelet transform was applied to the sequential data. The variables to be discriminated were the waveforms related to levels -4 and -5. The sum of the square values at each step was compared at levels -4 and -5. Downstairs walking could be discriminated from other types of walking, showing the largest value for level -5. Walking at horizontal level was compared with upstairs walking for level -4. It was possible to discriminate the continuous dynamic responses to walking by the wavelet transform.

Abstract:In this study, we attempted to discriminate the acceleration signal for horizontal level and stairway walking using wavelet-based fractal analysis method. The acceleration signal was measured close to the center of gravity of the body, while the subjects walked continuously in the corridor and up and down the stairs. We used the wavelet-based fractal analysis method to discriminate walking pattern. The parameter H which is related directly to the fractal dimension was estimated by the wavelet coefficient and was changed into low value during walking upstairs. By manually setting the threshold level for individual, it was possible to discriminate walking upstairs from the other walking type. However, the common feature among subjects was not shown between level walking and walking downstairs.

Abstract
Atopic dermatitis (AD) is a chronic or chronically relapsing, eczematous, severely pruritic skin disorder associated with skin barrier dysfunction. The lesional skin of AD exhibits T helper 2 (TH 2)-deviated immune reactions. Interleukin-31 (IL-31), preferentially produced from TH 2 cells, is a potent pruritogenic cytokine, and its systemic and local administration induces scratching behavior in rodents, dogs and monkeys. Recent clinical trials have revealed that administration of an anti-IL-31 receptor antibody significantly alleviates pruritus in patients with AD. In this review, we summarize recent topics related to IL-31 and its receptor with special references to atopic itch.

Abstract
Ion implantation through nanometer-scale apertures (nano-apertures) is a promising method to precisely position ions in silicon matrices, which is a requirement for next generation electronic and quantum computing devices. This paper reports the application of atom probe tomography (APT) to investigate the three-dimensional distribution of germanium atoms in silicon after implantation through nano-aperture of 10 nm in diameter, for evaluation of the amount and spatial distribution of implanted dopants. The experimental results obtained by APT are consistent with a simple simulation with consideration of several effects during lithography and ion implantation, such as channeling and resist flow.

Abstract
BACKGROUND AND PURPOSE Few studies have examined why some patients with dementia stop attending medical consultations. We conducted a retrospective study to investigate factors associated with discontinuous clinic attendance. METHODS Participants were 988 patients with dementia from university hospital (UH) clinics and affiliated local hospital (LH) clinics. We compared continuous and discontinuous attenders on cognitive and affective functions and activities of daily living (ADL), and also compared UH and LH patients (UH: continuous, n = 176; discontinuous, n = 207; LH: continuous, n = 418; discontinuous, n = 187). RESULTS The total annual rate of discontinuation was 8.0%, and the mean period of attendance before discontinuation was 2.2 ± 2.4 years (UH, 2.8 ± 3.0; LH, 1.5 ± 1.3, P < 0.01). Scores for the Mini-Mental State Examination, Hasegawa Dementia Scale - Revised, Geriatric Depression Scale, apathy scale, Abe's behavioral and psychological symptoms of dementia (BPSD) score, and ADL were significantly worse in the discontinuous group than the continuous group for both UH and LH patients (P < 0.01). The best predictor of discontinuation was ADL decline (UH and LH) and Abe's BPSD score (UH). The most common reason for discontinuation was returning to the family doctor (39.1% for UH), and cessation of hospital attendance at their own discretion (35.3% for LH). CONCLUSIONS We identified the main reasons for discontinuation of attendance as returning to the family doctor and cessation of hospital attendance at their own discretion. The best predictors of discontinuation were ADL decline and worsening BPSD. There were significant differences in discontinuation between UH and LH patients with dementia.

Abstract
BACKGROUND AND PURPOSE The influence of metabolic syndrome (MetS) on cognitive and affective functions in patients with Alzheimer's disease (AD) was examined. METHODS A total of 570 AD patients were divided into two subgroups depending on waist circumference (WC) (normal versus achieving Japanese diagnostic criteria of MetS). Afterwards, the AD control subgroup was defined as those normal WC patients with no vascular risk factors (VRFs). The AD with MetS (AD-MetS) subgroup was defined as the MetS WC group who had two or more VRFs to qualify as having MetS. Cognitive and affective functions, insulin resistance, vascular endothelial function and white matter changes between AD-MetS and AD controls were compared. RESULTS Scores on the Mini-Mental State Examination, Hasegawa Dementia Score-Revised, Frontal Assessment Battery and Montreal Cognitive Assessment were worse in the AD-MetS group than in AD controls, but the difference was not significant. Some analyses were conducted twice, once including all patients and once including only late-elderly patients. Scores on the Geriatric Depression Scale were found to be significantly higher for AD-MetS than for AD controls (all ages, late-elderly), as were those for apathy (late-elderly). Furthermore, both the homeostasis model assessment of insulin resistance and reactive hyperemia index scores were significantly worse in AD-MetS than in AD controls, whilst white matter changes showed a tendency to be worse. CONCLUSIONS Greater cognitive and affective decline occurs in patients with AD-MetS than in those without. Further, insulin resistance and vascular endothelial dysfunction are strongly correlated with AD-MetS before pathological white matter changes can be observed.

Abstract
AIMS This study aimed to identify the main active component of Lactobacillus brevis KB290 (KB290) that is responsible for enhanced cell-mediated cytotoxic activity of mouse splenocytes Live KB290, a probiotic strain derived from a Japanese traditional pickle, was previously reported to modulate innate immune responses as affecting on cell-mediated cytotoxic activity of mouse splenocytes. METHODS AND RESULTS We used live KB290, heat-killed KB290, a derivative strain (Lact. brevis KB392) with different amounts of cell-bound exopolysaccharide (EPS-b), and a crude extract of EPS-b from KB290 cell surface. Female BALB/c mice were fed a diet containing 10(10) CFU live KB290, 10(10) CFU live KB392, 15 mg heat-killed KB290 or 600 μg crude extract of EPS-b for 1 day. Live KB290 (P < 0.01), heat-killed KB290 (P < 0.05) and crude EPS-b at 600 μg (P < 0.05) per mouse significantly enhanced cytotoxic activity; however, live KB392 had no effect. CONCLUSIONS Both live and heat-killed KB290 and crude EPS-b significantly enhanced cytotoxic activity of mouse splenocytes. SIGNIFICANCE AND IMPACT OF THE STUDY We demonstrated that EPS-b produced by KB290 has a critical role in enhancing cell-mediated cytotoxic activity in mouse spleen.

Abstract
UNLABELLED We investigated the efficacy of dietary consumption of Lactobacillus brevis KB290 (KB290) against influenza in humans by a preliminary intervention study on elementary schoolchildren, using a commercially available probiotic drink. Subjects were divided into Groups A and B, and an open-label, parallel-group trial was conducted in two 8-week periods at a 1-month interval in winter 2013/2014. Group A was provided with a bottle of the test drink containing KB290 (about 6 billion colony-forming units) every school day in the first period and had no treatment in the second period, and vice versa for Group B. Epidemic influenza was not observed during the first period and only two of 1783 subjects were diagnosed. In the second period, the incidence of influenza in Groups A (no treatment) and B (provided the test drink) was 23·9 and 15·7%, respectively, and the difference was statistically significant (P < 0·001). The reduction in the incidence of influenza by KB290 consumption was especially remarkable in unvaccinated individuals. This is believed to be the first study to show a probiotic food reducing the incidence of influenza in schoolchildren, although further studies are needed to confirm the effectiveness of the probiotic strain KB290. SIGNIFICANCE AND IMPACT OF THE STUDY We demonstrated a reduction in the incidence of influenza in 1089 schoolchildren by continual intake of a probiotic drink containing Lactobacillus brevis KB290 (KB290), isolated from a traditional Japanese pickle 'Suguki'. The effect was especially evident in subjects not inoculated with influenza vaccine. This is believed to be the first report to show reduced incidence of influenza in schoolchildren taking a probiotic food. Further studies are needed to confirm the effectiveness of the probiotic strain KB290, which may be useful in the development of potential anti-influenza agents derived from common foods.

Abstract
Poor oral health and hygiene are increasingly recognized as major risk factors for pneumonia among the elderly. To identify modifiable oral health-related risk factors, we prospectively investigated associations between a constellation of oral health behaviors and incident pneumonia in the community-living very elderly (i.e., 85 years of age or older). At baseline, 524 randomly selected seniors (228 men and 296 women; mean age, 87.8 years) were examined for oral health status and oral hygiene behaviors as well as medical assessment, including blood chemistry analysis, and followed up annually until first hospitalization for or death from pneumonia. During a 3-year follow-up period, 48 events associated with pneumonia (20 deaths and 28 acute hospitalizations) were identified. Among 453 denture wearers, 186 (40.8%) who wore their dentures during sleep were at higher risk for pneumonia than those who removed their dentures at night (log rank P = 0.021). In a multivariate Cox model, both perceived swallowing difficulties and overnight denture wearing were independently associated with an approximately 2.3-fold higher risk of the incidence of pneumonia (for perceived swallowing difficulties, hazard ratio [HR], 2.31; and 95% confidence interval [CI], 1.11-4.82; and for denture wearing during sleep, HR, 2.38; and 95% CI, 1.25-4.56), which was comparable with the HR attributable to cognitive impairment (HR, 2.15; 95% CI, 1.06-4.34), history of stroke (HR, 2.46; 95% CI, 1.13-5.35), and respiratory disease (HR, 2.25; 95% CI, 1.20-4.23). In addition, those who wore dentures during sleep were more likely to have tongue and denture plaque, gum inflammation, positive culture for Candida albicans, and higher levels of circulating interleukin-6 as compared with their counterparts. This study provided empirical evidence that denture wearing during sleep is associated not only with oral inflammatory and microbial burden but also with incident pneumonia, suggesting potential implications of oral hygiene programs for pneumonia prevention in the community.

Abstract
Background. Patients with renal anemia who show a poor response to erythropoietin might have iron insufficiency. Reticulocyte hemoglobin content (CHr) was measured in hemodialysis patients, and its potential as a marker for iron status was assessed by comparing CHr with ordinary markers. Methods. Ninety-one patients receiving maintenance hemodialysis were enrolled. Venous sampling was performed twice, at a 3-month interval. During the interval, none of the patients received any iron agent and there was no alteration in their erythropoietin doses. CHr was measured with an automated blood cell counter. Simultaneously, ordinary markers for iron status, such as hematocrit (Ht), mean hemoglobin content (CH), serum iron (Fe), ferritin (Fr), and transferrin saturation (TSAT), were measured. CHr was compared with these markers. Results. CHr randed from 24.1 to 34.7 pg, with a mean of 31.0 pg. CHr correlated with CH (P < 0.001), Fr (P < 0.01), Fe (P < 0.001), and TSAT (P < 0.001), but not with Ht. When patients were divided into two groups according to the CHr : CH ratio (CHr : CH ≧ 1 and CHr : CH < 1), there was no difference in any parameter between the two groups in the first measurement. In the second measurement, done after a 3-month interval, patients with CHr : CH ≧ 1 showed significantly higher values for CHr (P < 0.001), CH (P < 0.01), Fe (P < 0.05), and TSAT (P < 0.05) than patients with CHr : CH < 1. Conclusions. It was suggested that the CHr : CH ratio would predict changes in the state of iron supply. CHr might be a potential marker for monitoring renal anemia.

Abstract
We developed a particle nanoimprinting technique assisted by the array of core-shell particles. Core-shell particles composed of a solid core of polystyrene and a soft shell were prepared by soap-free emulsion polymerization and subsequently seeded polymerization. By the Langmuir-Blodgett method, particles were arranged into a closely packed 2D array over the water surface and transferred onto a polystyrene (PS) substrate at a regular interval. The PS substrate was heated up above its glass transition temperature (Tg) by either UV irradiation using a high-pressure Hg lamp or heat treatment in a temperature-controlled incubator. It could be observed that a nanopatterned indented surface was formed through the denting of particles into the PS substrate (particle nanoindenting). By the detachment of particles from the substrate by ultrasonication in ethanol, nanoholes were produced over the surface (particle nanoimprinting). The depth and the wall of nanoholes and their interval were tunable by the shell thickness and the 2D packing ratio of core-shell particle monolayers. The contact angle decreased from 70 degrees of the pristine particle monolayer to 13 degrees by the particle nanoindenting, and again increased to 50 degrees by detaching the particles from the substrate to create the nanoholes. The use of nanoholes as zepto-litter volume vessels enabled us to produce and arrange nanocrystals, such as NaCl and CaCO3 (zepto-reactor).

Abstract
Scaffolds play a key role in the process of regeneration and morphogenesis of tissue or organ. We have developed a novel sonication decellularization system to prepare decellularized bio-scaffolds in a short treatment time. The aim of the study is to investigate sonication decellularization condition that completely decellularize meniscus can be changed as well as to maintain the biomechanical parameters of scaffolds. The meniscus samples were decellularized using sonication treatment. The treated samples were evaluated histologically by EVG for cell removal, picrosirius red for content of collagen type I and III, and safranin-O/fast green staining for content of glycosaminoglycan, and SEM for observation of scaffold surface. Indentation apparatus was used to analyze the unconfined deformation under load of native and decellularized menisci. The load parameters which are stiffness, compression and residual force were not significantly different compare with native and sonicated scaffolds. However, the content of extracellular matrix and its fiber alignment changed significantly due to sonication treatment as observed by SEM and safranin-O/fast green staining, respectively. The removal of immunogenic cell components by sonication decellularization as well as maintain its biomechanical strength of decellularized scaffolds, so that it has potential to use as an implant material for tissue engineering of menisci.

Abstract
To reveal the signaling pathway leading to oncogenecity of human cancer cells, we examined the expression and tyrosine-phosphorylation of phosphatidylinositol (PI)-3 kinase in cancer cell lines. Of the 14 cell lines examined, two poorly differentiated human gastric cancer cell lines, NUGC-4 and MKN-45, which were previously found to have aberrant elevation of tyrosine phosphorylation showed elevated levels of PI-3 kinase 85-kDa subunit expression. In these cells, tyrosine-phosphorylation and overall activity of PI-3 kinase were apparently elevated, compared with normal human fibroblasts and another well differentiated gastric cancer cell line, MKN-28. Treatment of these cells with tyrosine kinase inhibitor, genistein, strongly suppressed the PI-3 kinase activity. Furthermore, wortmannin, a potent inhibitor of PI-3 kinase, strongly suppressed the growth of these gastric cancer cells. These results suggest that the growth signaling via tyrosine phosphorylation is required for the activation of PI-3 kinase in NUGC4 and MKN-45, and that this activation plays an important role in oncogenic growth of these cells. However, these two cell lines showed different responses of PI-3 kinase to acid-treatment and tyrosine kinase inhibitors. In MKN-45, activation of PI-3 kinase appeared to be constitutive, and could be relevant to the oncogenic nature of the cell line.

Abstract
The aim of the present study was to improve cytoplasmic maturation of porcine oocytes by the addition of lycopene into in vitro maturation (IVM) media. We designed six experimental groups; IVM medium was supplemented with 10 IU/ml FSH, FSH and 10 IU/ml human chorionic gonadotrophin (hCG), or FSH and 7 μm lycopene in the first half of the IVM culture (0-22 h) followed by further culture (22-44 h) with or without hCG. The addition of lycopene into IVM media delayed the interruption of communication between an oocyte and the cumulus cells. Although meiotic competence was similar among the six groups, the glutathione level of matured oocytes was significantly higher in the lycopene-supplemented group (9.89 pmol per oocyte) than that in other groups (7.25 and 7.81 pmol per oocyte). Fertilization rate was significantly improved in lycopene-supplemented groups (58.3%) more than that in the group supplemented with FSH only (43.1%), whereas there were no differences in developmental competence among the groups (blastocyst rate: 20.1-29.5%). These results indicate that insufficient cytoplasmic maturation during conventional IVM resulted by disconnection of the gap junction between an oocyte and the cumulus cells in the early phase during IVM culture. We concluded that lycopene induced a prolonged sustainment of gap junctional communication between an oocyte and the cumulus cells during porcine IVM culture, which was an effective cytoplasmic maturation of porcine IVM oocytes.

Abstract
BACKGROUND Previous small-sized studies showed lower thymidylate synthase (TS) expression in adenocarcinoma of the lung, which may explain higher antitumor activity of TS-inhibiting agents such as pemetrexed. PATIENTS AND METHODS To quantitatively measure TS gene expression in a large-scale Japanese population (n = 2621) with primary lung cancer, laser-captured microdissected sections were cut from primary tumors, surrounding normal lung tissues and involved nodes. RESULTS TS gene expression level in primary tumor was significantly higher than that in normal lung tissue (mean TS/β-actin, 3.4 and 1.0, respectively; P < 0.01), and TS gene expression level was further higher in involved node (mean TS/β-actin, 7.7; P < 0.01). Analyses of TS gene expression levels in primary tumor according to histologic cell type revealed that small-cell carcinoma showed highest TS expression (mean TS/β-actin, 13.8) and that squamous cell carcinoma showed higher TS expression as compared with adenocarcinoma (mean TS/β-actin, 4.3 and 2.3, respectively; P < 0.01); TS gene expression was significantly increased along with a decrease in the grade of tumor cell differentiation. There was no significant difference in TS gene expression according to any other patient characteristics including tumor progression. CONCLUSION Lower TS expression in adenocarcinoma of the lung was confirmed in a large-scale study.

Abstract
Dextransucrase and invertase of some strains of Streptococcus mutans were examined by immunodiffusion with antisera against enzymes purified from strain HS-6 (Bratthall's serotype a). Both antisera cross-reacted with crude enzyme preparations from the other serotype a (strains HS-1 and AHT) and d organisms (strains KIR, OMZ176, and OMZ65) but not with those from serotype b (strains FA-1 and BHT) or c organisms (strains GS-5, Ingbritt, and NCTC 10449). Based upon the antiserum used, the orders of antigenic similarity of the cross-reacting enzymes to the HS-6 enzymes were HS-6 > HS-1 > AHT = KIR = OMZ176 = OMZ65 for dextransucrase and HS-6 = HS-1 > AHT = KIR = OMZ176 = OMZ65 for invertase. It was found that the enzymes from serotype a organisms were not always antigenically homogeneous, as seen between strains HS-6, HS-1, or AHT for dextransucrase, and between the HS group and strain AHT for invertase. Antiserum against the HS-6 dextransucrase markedly inhibited the heterologous dextransucrases of serotype a organisms with the exception of strain HS-1 and d organisms, with or without the addition of dextran.

Abstract
The objective of this study was to investigate the effects of oocyte selection using brilliant cresyl blue (BCB) and culture density during individual in vitro maturation (IVM) on porcine oocyte maturity and subsequent embryo development using a chemically defined medium. Cumulus-oocyte complexes (COCs) were classified as BCB-positive or BCB-negative after exposure to a BCB solution for 90 min. The classified COCs were matured in a group (15 COCs per 100-microL droplet) or individually (1 COC per 1-, 2.5-, 5-, or 10-microL droplet). Meiotic competence, intraoocyte glutathione concentration, and developmental competence after intracytoplasmic sperm injection were monitored. The BCB selected oocytes competent for nuclear and cytoplasmic maturation. Furthermore, meiotic competence for oocytes matured individually in a 5-microL droplet was superior (P<0.05) to that of oocytes matured in a 1-microL droplet. Also, the culture density in a 5-microL droplet during IVM resulted in a higher (P<0.05) rate of cleaved embryos than that in a 1-microL droplet and produced a similar rate of blastocysts compared with that of a group culture system. Conversely, BCB selection did not improve cleavage and blastocyst formation. In conclusion, it was possible to predict porcine oocytes competent for maturation using oocyte selection with BCB. Moreover, a 5-microL droplet during the individual IVM culture was most suitable for oocyte maturation and subsequent embryo development, although every culture density used in this study supported development up to the blastocyst stage.

Abstract
This study describes the adsorptive property of vitamins on HA and the effect of the HA adsorbed vitamin on the alkaline phosphatase (ALP) activity for effective use as a bone graft substitute. The vitamins used were calciferol (D3), menaquirone (K2) and 25-hydroxycholecalciferol (25(OH)D3). These vitamins were adsorbed on HA at 4, 10, 20, 37 and 50 degrees C. The adsorption amount was constant below 20 degrees C, and decreased as the incubation temperature increased over 20 degrees C. The order of the adsorption amount was: 25(OH)D3 > K2 > D3. The HA adsorbed vitamins (HA/D3, HA/25(OH)D3 and HA/K2) were suspended in physiological saline for 48 h for the release test. The release ratio of all vitamins increased with incubation time. The order of the release ratio was: 25(OH)D3 > K2 > D3, which was proportional to that of the adsorption amount. The ALP activity of MC3T3-E1 osteoblast-like cells on HA, HA/D3, HA/25(OH)D3 and HA/K2 was also investigated. The ALP activity was higher on HA/25(OH)D3 than on any other samples. However, HA/K2 and HA/D3 showed similar ALP activity to HA.
