Abstract
OBJECTIVE To examine the association between rheumatoid arthritis (RA) and oral hypofunction (OHF) using propensity score matching (PSM) to adjust for differences between older adults with RA and the general older adult population. METHODS We conducted a cross-sectional survey among 189 older adults with RA in 2019 (mean age, 71.9 ± 3.6) and 47 178 independent older adult residents in 2016 (mean age, 71.6 ± 4.0), respectively. The questionnaire covered information on socio-demographic characteristics and OHF for both groups. Age, sex, educational level and smoking history were used to determine PSM. Prevalence ratios (PRs) and 95% confidence intervals (CIs) of self-reported OHF (fewer remaining teeth, decreased masticatory function, deterioration of swallowing function and oral dryness) were estimated using Poisson regressions. RESULT OHF was observed in 44.4% of patients with RA and 27.5% of residents. Before PSM, the prevalence of OHF among patients with RA was higher than that of residents (PR, 1.75; 95% CI, 1.50-2.05). After PSM, there were 189 patients with RA and residents, and the prevalence of OHF among patients with RA was still higher (PR, 1.61; 95% CI, 1.22-2.13). Poisson regression showed that the prevalence of 19 or fewer teeth (PR, 1.06; 95% CI, 0.82-1.36), difficulties eating tough foods (PR, 1.18; 95% CI, 0.90-1.55), difficulties swallowing tea or soup (PR, 1.77; 95% CI, 1.19-2.63), and dry mouth (PR, 2.79; 95% CI, 1.90-4.07) was higher among patients with RA than residents. CONCLUSION Compared with the general older adult population, patients with RA have a higher prevalence of self-reported OHF.

Abstract
The T2K experiment presents new measurements of neutrino oscillation parameters using 19.7 ( 16.3 ) × 10 20 protons on target (POT) in (anti-)neutrino mode at the far detector (FD). Compared to the previous analysis, an additional 4.7 × 10 20 POT neutrino data was collected at the FD. Significant improvements were made to the analysis methodology, with the near-detector analysis introducing new selections and using more than double the data. Additionally, this is the first T2K oscillation analysis to use NA61/SHINE data on a replica of the T2K target to tune the neutrino flux model, and the neutrino interaction model was improved to include new nuclear effects and calculations. Frequentist and Bayesian analyses are presented, including results on sin 2 θ 13 and the impact of priors on the δ CP measurement. Both analyses prefer the normal mass ordering and upper octant of sin 2 θ 23 with a nearly maximally CP-violating phase. Assuming the normal ordering and using the constraint on sin 2 θ 13 from reactors, sin 2 θ 23 = 0 . 561 - 0.032 + 0.021 using Feldman-Cousins corrected intervals, and Δ m 32 2 = 2 . 494 - 0.058 + 0.041 × 10 - 3 eV 2 using constant Δ χ 2 intervals. The CP-violating phase is constrained to δ CP = - 1 . 97 - 0.70 + 0.97 using Feldman-Cousins corrected intervals, and δ CP = 0 , π is excluded at more than 90% confidence level. A Jarlskog invariant of zero is excluded at more than 2 σ credible level using a flat prior in δ CP , and just below 2 σ using a flat prior in sin δ CP . When the external constraint on sin 2 θ 13 is removed, sin 2 θ 13 = 28 . 0 - 6.5 + 2.8 × 10 - 3 , in agreement with measurements from reactor experiments. These results are consistent with previous T2K analyses.

Abstract
BACKGROUND/AIMS Although undifferentiated gastric cancer (UGC) diagnosed after Helicobacter pylori eradication (HPE) carries a poor prognosis, characteristics of post-HPE UGC have not been evaluated in detail because of its low incidence. Therefore, we compared the clinicopathologic characteristics of UGC and differentiated gastric cancers (DGC) diagnosed after successful HPE. METHODS GC lesions from patients who had successfully completed HPE and who had undergone upper gastrointestinal endoscopy between January 2004 and March 2016 were analyzed. Tumors were divided into DGC and UGC groups. Clinicopathologic factors of background and tumor characteristics were compared using univariate and multiple logistic analyses. RESULTS A total of 129 tumors from 115 patients were evaluated; 113 tumors were in the DGC group and 16 in the UGC group. Depressed-type tumors (P = 0.024) and sub-submucosal invasion (P<0.001) were significantly higher in the UGC group. The UGC group had larger tumor diameters (25.9±7.3 mm) than the DGC group (13.2±10.2 mm) (P<0.001). Multivariate analysis showed that female sex (odds ratio [OR] 3.24, 95%CI:1.02-10.37; P = 0.047) and absent follow-up (OR 4.99, 95%CI:1.60-15.57; P = 0.006) were significant independent risk factors for UGC. The DGC group showed a gradually decreasing temporal trend by trend test (P = 0.015), while the UGC group showed a relatively constant incidence over time, although the number of cases was small. CONCLUSION UGC was diagnosed even after long time spans following HPE, although the number of cases was small. Female sex, and especially absent follow-up, were risks for post-HPE UGC, suggesting that diligent long-term follow-up after HPE is essential.

Abstract
Abstract
Study question
This study was to investigate effect of SERa on the fertilization rate, embryonic development after ICSI, and clinical and perinatal outcomes after single blastocyst transfer.
Summary answer
SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.
What is known already
Based on findings that the risk of congenital abnormalities in the newborn is higher in ovum with SERa in the cytoplasm, the Istanbul consensus workshop at the 2011 meeting of the ESHRE recommended against fertilizing ovum with SERa due to these risks. However, there have been several reports of healthy infants born from embryos derived from SERa, suggesting that, while more long-term follow-up is necessary, healthy births are possible from such embryos. In 2017, the 2011 recommendations were reviewed in the Alpha/ESHRE consensus (Vienna), which said the approach should be determined on a case-by-case basis.
Study design, size, duration
We retrospectively investigated 23,007 oocytes which was retrieved between January 2016 and March 2020. Of these, 1,038 oocytes (4.5%) with visible SERa comprised SERa (+), while 21,969 oocytes (95.5%) without SERa comprised SERa (-).
Participants/materials, setting, methods
SERa were observed under the microscopy after denudation. The rate of fertilization, good-quality day-3 embryos, good-quality day-5 blastocysts, and day-5, 6 or 7 blastocysts were evaluated for both groups. We also compared the rate of clinical pregnancy, live birth, miscarriage, and birth defects in single blastocyst transfer between SERa (+) derived 114 blastocysts and SERa (-) derived 6,290 blastocysts from January 2016 and December 2018.
Main results and the role of chance
The results are shown. 2PN fertilization rate outcomes after ICSI (SERa(-) eggs vs. SERa(+)eggs),81.4%(17,873/21,969) vs.79.4% (823/1,038),and good-quality day3 rate was 61.1%(10,927/17,873)vs.60.9% (501/823) which was not significantly different. Good-quality day5 blastocyst rate was 46.5% (7,876/16,955) vs. 39.8%(304/763), and day 5 blastocyst success rate was 60.8% (10,317/16,955) vs.54.3% (414/763), which were both significantly lower with SERa(+). (P < 0.001) The day 6 blastocyst success rate was 69.9% (11,849/16,955) vs. 65.5% (500/763) (P = 0.01), and the day 7 blastocyst success rate was 70.9% (12,024/16,955) vs. 67.5% (515/763) (P = 0.04), which were all significantly lower with SERa(+).The clinical pregnancy rate was 39.4% (2,481/6,290) vs. 35.1% (40/114), the live birth rate was 27.7% (1,745/6,290) vs. 26.3% (30/114), and the miscarriage rate was 27.5% (683/2,481) vs. 20.0% (8/40) and the congenital abnormality rate was 1.6% (29/1,757) vs. 0% (0/30) for SERa(-) embryos and SERa(+) embryos, respectively, which were not significantly different. Blastocyst derived from oocytes with SERa has similar clinical and perinatal outcomes with those of oocytes without SERa. Significant differences were examined using the chi-squared test, with p < 0.05, indicating a significant difference.
Limitations, reasons for caution
Embryos derived SERa (+) were transferred when the patient did not want any more oocytes retrievals, no embryos derived SERa (-) were available, and only if the couple desired embryo transfer after the problems associated with SERa (+) embryos were fully explained.
Wider implications of the findings
To the best of our knowledge, this study is the largest number of live births investigating the outcome of SERa (+) derived embryos. SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.

Abstract
Antibiotics disrupt normal gut microbiota and cause dysbiosis, leading to a reduction in intestinal epithelial barrier function. Disruption of the intestinal epithelial barrier, which is known as “leaky gut”, results in increased intestinal permeability and contributes to the development or exacerbation of gastrointestinal diseases such as inflammatory bowel disease and irritable bowel syndrome. We have previously reported on a murine model of intestinal epithelial barrier dysfunction associated with dysbiosis induced by the administration of ampicillin and vancomycin. Saireito, a traditional Japanese herbal medicine, is often used to treat autoimmune disorders including ulcerative colitis; the possible mechanism of action and its efficacy, however, remains unclear. In this study, we examined the efficacy of Saireito in our animal model for leaky gut associated with dysbiosis. C57BL/6 mice were fed a Saireito diet for the entirety of the protocol (day1-28). To induce colitis, ampicillin and vancomycin were administered in drinking water for the last seven consecutive days (day22-28). As previously demonstrated, treatment with antibiotics caused fecal occult bleeding, cecum enlargement with black discoloration, colon inflammation with epithelial cell apoptosis, and upregulation of pro-inflammatory cytokines. Oral administration of Saireito significantly improved antibiotics-induced fecal occult bleeding and cecum enlargement by suppressing inflammation in the colon. Furthermore, Saireito treatment ensured the integrity of the intestinal epithelial barrier by suppressing apoptosis and inducing cell adhesion proteins including ZO-1, occludin, and E-cadherin in intestinal epithelial cells, which in turn decreased intestinal epithelial permeability. Moreover, the reduced microbial diversity seen in the gut of mice treated with antibiotics was remarkably improved with the administration of Saireito. In addition, Saireito altered the composition of gut microbiota in these mice. These results suggest that Saireito alleviates leaky gut caused by antibiotic-induced dysbiosis. Our findings provide a potentially new therapeutic strategy for antibiotic-related gastrointestinal disorders.

Abstract
OBJECTIVES We aimed to evaluate the clinical value of an entire-circumferential intraoperative frozen section analysis (e-IFSA) for the complete resection of superficial squamous cell carcinoma (SCC) of the tongue. MATERIALS AND METHODS A total 276 specimens from 51 patients with pT1-2, N0, mucosal or submucosal invasion SCC were analyzed to evaluate the diagnostic accuracy of the e-IFSA and the added value of the e-IFSA to iodine staining. The e-IFSA results were compared with the final histologic results obtained using permanent sections. All specimens for the e-IFSA were taken over the entire circumference 5 mm outside from the iodine unstained areas. The outline of the main resected specimen after taking these outer mucosal specimens were defined as the surgical margins determined by iodine staining alone. RESULTS The e-IFSA results were in excellent agreement with final histological results (Cohen's kappa value: 0.85) and the e-IFSA showed high sensitivity (100%) and high negative predictive value (100%). The actual complete resection rate with an e-IFSA was 100% (51/51), and no patient required additional resection after surgery. In contrast, 10/51 patients (20%) patients showed residual atypical mucosal epithelium at or beyond the margin determined by iodine staining alone; this difference was statistically significant (P = 0.002). The 5-year local control rate and 5-year overall survival rate after this procedure were both 100%. CONCLUSION An e-IFSA has additional value when performed in conjunction with iodine staining. An e-IFSA would be useful for achieving complete resection of superficial SCC of the tongue.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder in the intestine, and the dysfunction of intestinal epithelial barrier (IEB) may trigger the onset of IBD. Secretory leukocyte protease inhibitor (SLPI) is a serine protease inhibitor that has been implicated in the tissue-protective effect in the skin and lung. We found that SLPI was induced in lipopolysaccharides-treated colon carcinoma cell line and in the colon of dextran sulfate sodium (DSS)-treated mice. SLPI-deficient mice were administered DSS to induce colitis and sustained severe inflammation compared with wild-type mice. The colonic mucosa of SLPI-deficient mice showed more severe inflammation with neutrophil infiltration and higher levels of proinflammatory cytokines compared with control mice. Moreover, neutrophil elastase (NE) activity in SLPI-deficient mice was increased and IEB function was severely impaired in the colon, accompanied with the increased number of apoptotic cells. Importantly, we demonstrated that DSS-induced colitis was ameliorated by administration of protease inhibitor SSR69071 and recombinant SLPI. These results suggest that the protease inhibitory activity of SLPI protects from colitis by preventing IEB dysfunction caused by excessive NE activity, which provides insight into the novel function of SLPI in the regulation of gut homeostasis and therapeutic approaches for IBD.

Abstract
Mutations in RAS or BRAF are associated with poor prognosis and resistance to epidermal growth factor receptor (EGFR)-targeted therapy in colorectal cancer (CRC). Despite their common ability to activate downstream genes such as MEK and ERK, the therapeutic benefit of MEK inhibitors for patients with RAS/BRAF mutant CRC is limited, highlighting the need for biomarkers to predict the efficacy of MEK inhibition. Previously, we reported that a change in phosphorylation of ribosomal protein S6 (pS6) after MEK inhibition was significantly associated with sensitivity to MEK inhibition in gastric cancer cells. Here, we investigated the value of the response in pS6 for predicting the efficacy of trametinib, a MEK inhibitor, in patients with RAS/BRAF mutant CRC using patient-derived CRC organoids. We found that a subset of CRC cell lines and organoids were sensitive to trametinib. The change in phosphorylated ERK, a downstream molecule of the RAS/RAF/MEK pathway, was not significantly associated with trametinib sensitivity. On the other hand, only those with sensitivity showed a reduction of pS6 levels in response to trametinib. The change in pS6 after trametinib treatment was detectable by Western blotting, immunohistochemistry or immunocytochemistry. We also demonstrated an impact of MEK inhibition on pS6 in vivo using a xenograft model. Our data suggest that, in combination with patient-derived organoids, immunostaining-based detection of pS6 could be useful for prediction of trametinib sensitivity.

Abstract
BACKGROUND AND AIM Improvement of atrophic gastritis and intestinal metaplasia (IM) is considered to reduce the gastric cancer risk, but whether it can be achieved by H. pylori eradication (HPE) remains controversial. To evaluate the effect of HPE, we observed the gastric mucosa for up to17 years after HPE and sex differences in gastric mucosa. METHODS In total, 172 patients (94 males, 78 females) with HPE were enrolled. Annual histological evaluations were performed for up to 17 years. The grades of mononuclear cells, neutrophils, atrophy, IM in the antrum and corpus were evaluated using the updated Sydney system. RESULTS Relative to the pre-HPE period, atrophy had improved significantly 1 year after HPE in the antrum (1.50 ± 0.75 vs. 1.21 ± 1.25, P < 0.01) and corpus (0.59 ± 0.75 vs. 0.18 ± 0.52, P < 0.05). IM showed no significant change during 17 years after HPE at either biopsy site. Atrophy scores did not differ significantly between males and females. IM scores were significantly higher in males than in females before eradication (antrum, 0.67 ± 0.94 vs. 0.44 ± 0.77, P = 0.003, corpus, 0.20 ± 0.62 vs. 0.047 ± 0.21, P = 0.0027) and at most observation timepoints. CONCLUSIONS During 17 years after HPE, atrophy, but not IM, improved significantly at the greater curvatures of the antrum and corpus. IM was significantly more severe in males than in females. Careful follow-up after HPE based on sex differences in gastric mucosal characteristics is important.

Abstract
Aim Antioxidant therapy for with vitamin E appears to be effective for the treatment of nonalcoholic fatty liver disease (NAFLD). However, the mechanism of action and optimal therapeutic dosage is unclear. The present study was undertaken to examine whether the effects of α‐tocopherol (α‐Toc) on NAFLD are dose‐dependent in a diet‐induced obese model. Methods Male mice were fed standard chow, high‐fat (HF) diet, HF diet with low‐dose, or with high dose of α‐Toc supplementation. Histological findings, triglyceride content, and the levels of protein expression related to fatty acid synthesis/oxidation such as carnitine palmitoyltransferase I (CPT‐1) of liver were evaluated. In addition, 2‐tetradecylglycidic acid (TDGA), a CPT‐1 inhibitor, was administered to mice fed HF diet with low‐dose of α‐Toc. Finally, HepG2 cells in fat‐loaded environment were treated with 0–50 μM α‐Toc. Results Treatment of low‐dose of α‐Toc decreased HF‐induced hepatic fat accumulation, but this finding was not observed in treatment of high dose of α‐Toc. HF‐induced reduction of CPT‐1 was attenuated with low‐dose of α‐Toc but not with high dose of α‐Toc. TDGA suppressed the improvement of histological findings in liver induced by low‐dose of α‐Toc treatment. CPT‐1 expression in HepG2 cells increased in response to low‐dose of α‐Toc, but not in high dose. Conclusions Dual action of α‐Toc on CPT‐1 protein levels was observed. The effect of vitamin E on NAFLD may be not be dose‐dependent.

Abstract
Abstract
Introduction
Patients with heart failure are reported to have activated platelets leading to thrombotic events. Consequently, immature giant platelets are produced, and platelet distribution width (PDW) and mean platelet volume (MPV) increase. These platelet indices are easily, reasonably, and safely available by routine blood test and recently have been proposed as potential markers of cardiac events. However, little is known about the usefulness of platelet indices in patients with congenital heart disease (CHD).
Purpose
To test whether the hypothesis that PDW and MPV correlate to the severity of heart failure and have prognostic value in both future heart failure-related admission and thrombosis formation in patients with CHD.
Methods
We performed a retrospective, single-centre study that included 400 patients with CHD (median age, 34 years [range: 12–76]; 49% males; 35% single ventricular morphology), who were admitted in our institute between April 2014 and June 2017. We reviewed patients' medical records to assess their clinical information including medical history, blood sample data, and echocardiologic parameters. At first, we assessed the correlation between platelet indices and patients' clinical parameters. Next, we compared platelet indices before and after treatment for heart failure. Finally, using logistic regression and Kaplan-Meier analyses, we assessed prognostic factors of future heart failure-related admission and thrombosis formation.
Results
In multivariate analysis, a significant correlation was found between PDW and logBNP (brain natriuretic peptide) (p<0.001), haemoglobin (p=0.01), D-dimer (p=0.019), Fontan operation (p<0.001) and male sex (p<0.001); as well as between MPV and logBNP (p<0.001), D-dimer (p<0.001) and Fontan operation (p=0.002). Throughout treatment of heart failure, significant reduction was found both in PDW (average value before treatment = 14.2, after treatment = 13.2, p=0.002) and MPV (before = 11.2, after = 10.8, p=0.004). In multivariate logistic regression analysis, predictors of future heart failure-related admissions were PDW (hazard ratio [HR]: 1.365; 95% confidence interval [CI]: 1.005–1.768), MPV (HR: 1.472; 95% CI: 1.055–2.052), age (HR: 1.063; 95% CI: 1.010–1.119), and SpO2 under 85% (HR: 5.089; 95% CI: 1.350–19.18). Using the same analysis, predictors of thrombotic formation were PDW (HR: 1.998; 95% CI: 1.461–2.630), MPV (HR: 1.792; 95% CI: 1.155–2.781), logBNP (HR: 1.196, 95% CI: 1.085–1.320), D-dimer (HR: 1.024; 95% CI: 1.007–1.042) and male sex (HR: 3.071; 95% CI: 1.079–8.737). In addition, during median follow-up of 28 months, the Kaplan-Meier analysis showed an improvement in both heart failure and thrombosis-free survival in the low PDW, as well as the low MPV group.
Conclusion
Platelet volume indices correlate to severity of heart failure and have prognostic value for both cardiac and thrombotic events in patients with congenital heart disease.

Abstract
BACKGROUND Persistent Helicobacter pylori infection induces gastric mucosal atrophy, which is a precancerous condition. Hydrogen sulfide (H2 S), a gaseous biological transmitter, has been implicated in both the physiological functions of the gastrointestinal tract and its diseases. To understand gastric epithelial cell response against H pylori infection, we investigated the metabolic changes of gastric cancer cells co-cultured with H pylori and observed the modulation of endogenous H2 S production. MATERIALS AND METHODS Gastric cancer AGS cells were co-cultured with an H pylori standard strain possessing bacterial virulence factor CagA (ATCC 43504) and a strain without CagA (ATCC 51932). Three hours after inoculation, the cells were subjected to metabolomics analysis using gas chromatography-tandem mass spectrometry (GC-MS/MS). Orthogonal projections to latent structures discriminant analysis (OPLS-DA) and pathway analysis were performed. In addition, intracellular H2 S levels were measured by using HSip-1 fluorescent probe. RESULTS Results of OPLS-DA showed a significant difference between the metabolism of untreated control cells and cells inoculated with the H pylori strains ATCC 51932 or ATCC 43504, mainly due to 45 metabolites. Pathway analysis with the selected metabolites indicated that methionine metabolism, which is related to H2 S production, was the most frequently altered pathway. H pylori-inoculated cells produced more endogenous H2 S than control cells. Moreover, ATCC 43504-inoculated cells produced less H2 S than ATCC 51932-inoculated cells. CONCLUSIONS H pylori infection modulates endogenous H2 S production in AGS cells, suggesting that H2 S might be one of the bioactive molecules involved in the biological mechanisms of gastric mucosal disease including mucosal atrophy.

Abstract
BACKGROUND Helicobacter pylori CagA has been found to be immuno-dominant protein and utilized for the diagnosis of the infection with cagA-positive strains. It is important to characterize the peptide epitopes capable of detecting serum anti-CagA antibodies to understand CagA immunogenicity. METHODS Sera from 171 Japanese patients were subjected for the epitope mapping study. Eighty seven peptides were designed from the CagA consensus sequence and were used for ELISA protocol to test the serum samples. The reacting anti-CagA IgG amounts to specific peptides were measured and compared. RESULTS The study revealed a strong reactivity of two peptides (c7-NNTEPIYAQVNKKKAGQAT and c8-AGQATSPEEPIYAQVAKKV) in H. pylori-infected group. Interestingly, these two peptides contained the well-known EPIYA-A and EPIYA-B region, respectively, which are two out of three CagA phosphorylation domains. Tyrosine-phosphorylation of these peptides reduced their reactivity in most sera. Moreover, additional peptides' mapping and chimeric-peptides' experiments indicated that the amino acids (QV and KK) accommodated in right-side flanking regions of both EPIYA-motifs were essential for their strong reactivity, whereas the third EPIYA-motif containing peptide (c12-GRSASPEPIYATIDFDEA) with differing flanking amino acids was not reactive in most cases. CONCLUSIONS Our results suggest that the amino acid sequences constituted in the two reactive peptides are the important immunogenic regions of CagA which would be useful to develop next-generation peptide-based diagnostic assays.

Abstract
BACKGROUND The tumor immune microenvironment (TIME) of lung cancer brain metastasis is largely unexplored. We carried out immune profiling and sequencing analysis of paired resected primary tumors and brain metastases of non-small-cell lung carcinoma (NSCLC). PATIENTS AND METHODS TIME profiling of archival formalin-fixed and paraffin-embedded specimens of paired primary tumors and brain metastases from 39 patients with surgically resected NSCLCs was carried out using a 770 immune gene expression panel and by T-cell receptor beta repertoire (TCRβ) sequencing. Immunohistochemistry was carried out for validation. Targeted sequencing was carried out to catalog hot spot mutations in cancer genes. RESULTS Somatic hot spot mutations were mostly shared between both tumor sites (28/39 patients; 71%). We identified 161 differentially expressed genes, indicating inhibition of dendritic cell maturation, Th1, and leukocyte extravasation signaling pathways, in brain metastases compared with primary tumors (P < 0.01). The proinflammatory cell adhesion molecule vascular cell adhesion protein 1 was significantly suppressed in brain metastases compared with primary tumors. Brain metastases exhibited lower T cell and elevated macrophage infiltration compared with primary tumors (P < 0.001). T-cell clones were expanded in 64% of brain metastases compared with their corresponding primary tumors. Furthermore, while TCR repertoires were largely shared between paired brain metastases and primary tumors, T-cell densities were sparse in the metastases. CONCLUSION We present findings that suggest that the TIME in brain metastases from NSCLC is immunosuppressed and comprises immune phenotypes (e.g. immunosuppressive tumor-associated macrophages) that may help guide immunotherapeutic strategies for NSCLC brain metastases.

Abstract
BACKGROUND AND PURPOSE Corticobasal syndrome (CBS) is pathologically characterized by tau deposits in neuronal and glial cells and by reactive astrogliosis. In several neurodegenerative disorders, 18 F-THK5351 has been observed to bind to reactive astrocytes expressing monoamine oxidase B. In this study, the aim was to investigate the progression of disease-related pathology in the brains of patients with CBS using positron emission tomography with 18 F-THK5351. METHODS Baseline and 1-year follow-up imaging were acquired using magnetic resonance imaging and positron emission tomography with 18 F-THK5351 in 10 subjects: five patients with CBS and five age-matched normal controls (NCs). RESULTS The 1-year follow-up scan images revealed that 18 F-THK5351 retention had significantly increased in the superior parietal gyrus of the patients with CBS compared with the NCs. The median increases in 18 F-THK5351 accumulation in the patients with CBS were 6.53% in the superior parietal gyrus, 4.34% in the precentral gyrus and 4.33% in the postcentral gyrus. In contrast, there was no significant increase in the regional 18 F-THK5351 retention in the NCs. CONCLUSIONS Longitudinal increases in 18 F-THK5351 binding can be detected over a short interval in the cortical sites of patients with CBS. A monoamine oxidase B binding radiotracer could be useful in monitoring the progression of astrogliosis in CBS.

Abstract
This paper reports successful measurement of even-related potential (ERP) using candle-like dry microneedle electrodes, which can acquire high-quality electroencephalogram (EEG) from hairy parts without any pretreatment. In our previous work, we successfully measured spontaneous EEG activity and its application to assess the stress state of the subjects. ERPs originate from electrophysiological response to stimulus and are one of the most important indices to capture the cognitive and sensory activities. In this work, using the candle-like dry microelectrodes, we demonstrate successful measurement of ERPs elicited by oddball tasks. Two oddball tasks using pure tone stimuli and speech stimuli were assigned to the subjects, where EEG was acquired from the parietal region (Cz in international 10-20 system). Note that no pretreatment, such as removal of hairs and abrasion of the scalp, was applied. As a result, P300 and mismatch negativity (MMN) were successfully measured in the both oddball tasks from the averaged EEG after the stimuli. Based on these results and given the attractive natures of the candle-like dry microneedle electrodes; they do not need any skin treatment and conductive gels and they can measure EEG from the hairy parts, the developed electrodes will accelerate cognitive neuroscience research using ERPs.

Abstract
Current standards for radiological protection of the public have been uniformly established. However, individual differences in radiosensitivity are suggested to exist in human populations, which could be caused by nucleotide variants of DNA repair genes. In order to verify if such genetic variants are responsible for individual differences in radiosensitivity, they could be introduced into cultured human cells for evaluation. This strategy would make it possible to analyse the effect of candidate nucleotide variants on individual radiosensitivity, independent of the diverse genetic background. However, efficient gene targeting in cultured human cells is difficult due to the low frequency of homologous recombination (HR) repair. The development of artificial nucleases has enabled efficient HR-mediated genome editing to be performed in cultured human cells. A novel genome editing strategy, 'transcription activator-like effector nuclease (TALEN)-mediated two-step single base pair editing', has been developed, and this was used to introduce a nucleotide variant associated with a chromosomal instability syndrome bi-allelically into cultured human cells to demonstrate that it is the causative mutation. It is proposed that this editing technique will be useful to investigate individual radiosensitivity.

Abstract
High-fat diet (HFD)-induced alteration in the gut microbial composition, known as dysbiosis, is increasingly recognized as a major risk factor for various diseases, including colon cancer. This report describes a comprehensive investigation of the effect of agaro-oligosaccharides (AGO) on HFD-induced gut dysbiosis, including alterations in short-chain fatty acid contents and bile acid metabolism in mice. C57BL/6N mice were fed a control diet or HFD, with or without AGO. Terminal restriction fragment-length polymorphism (T-RFLP) analysis produced their fecal microbiota profiles. Profiles of cecal organic acids and serum bile acids were determined, respectively, using HPLC and liquid chromatography-tandem mass spectrometry systems. T-RFLP analyses showed that an HFD changed the gut microbiota significantly. Changes in the microbiota composition induced by an HFD were characterized by a decrease in the order Lactobacillales and by an increase in the Clostridium subcluster XIVa. These changes of the microbiota community generated by HFD treatment were suppressed by AGO supplementation. As supported by the data of the proportion of Lactobacillales order, the concentration of lactic acid increased in the HFD + AGO group. Data from the serum bile acid profile showed that the level of deoxycholic acid, a carcinogenic secondary bile acid produced by gut bacteria, was increased in HFD-receiving mice. The upregulation tended to be suppressed by AGO supplementation. Finally, results show that AGO supplementation suppressed the azoxymethane-induced generation of aberrant crypt foci in the colon derived from HFD-treated mice. Our results suggest that oral intake of AGO prevents HFD-induced gut dysbiosis, thereby inhibiting colon carcinogenesis.

Abstract
This paper reports a successful electroencephalogram (EEG) measurement from the hairy part of the scalp using a polymer-based dry microneedle electrode. The electrode consists of 25 pillars, each of which has a sharp microneedle on the top. Hairs are collected into the gaps of the pillars and the microneedles can reach the scalp surface. Since the microneedles can penetrate through the stratum corneum, no conductive gel is necessary to acquire high quality EEG. We experimentally investigated the pillar diameters in EEG measurement from the occipital region with hairs. The fabricated electrodes successfully measured EEG without any skin preparation or conductive gel.

Abstract
OBJECTIVE Steroid pulse therapy is used to relieve pancytopenias in our hospital and is effective in some patients. However, it is unclear which patients will benefit from such therapy. Thus, we retrospectively analyzed the clinical features of patients undergoing allogeneic hematopoietic stem cell transplantation who received steroid pulse therapy to facilitate recovery in their blood cell counts. METHODS Between 2004 and 2012, 24 patients underwent steroid pulse therapy and the medical records of 17 of these evaluable patients (11 men, 6 women) were retrospectively reviewed. Bone marrow smears were assessed to calculate the proportion of hemophagocytic macrophages just prior to receiving pulse therapy. RESULTS Steroid pulse therapy was started at a median of 15 days after transplantation (range, 10-28 days). The median white blood cell count was 0.02×10(3)/μL (range, 0.01-0.4×10(3)/μL). Eight patients responded to pulse therapy and subsequent engraftment was achieved in all responders. None of the patients who underwent cord blood transplantation responded to the pulse therapy. Among the non-responders, only two patients achieved engraftment and four of nine non-responders died within one month. When evaluating the efficacy of steroid pulse therapy according to the ferritin level and proportion of hemophagocytic macrophages among patients undergoing bone marrow or peripheral blood stem cell transplantation, both values were higher in responders than in non-responders. CONCLUSION We speculate that responders have a hemophagocytic syndrome which is responsive to steroid pulse therapy. Thus, our results imply that the use of ferritin levels in combination with the proportion of hemophagocytic macrophages may be useful for the early detection of potential hemophagocytic syndrome after hematopoietic stem cell transplantation.

Abstract
The aims of this study were to introduce a novel electronic system for reliable evaluation of the non-functional tooth contact in patients with temporomandibular disorders (TMDs) and investigate the possible associations between the non-functional tooth contact and some characteristics of the patients with TMD. We designed and installed a software program to send emails regarding the non-functional tooth contact to the subjects' preregistered cellular phones at intervals of 20 ± 9 min daily for 10 consecutive days. Twelve patients with TMD and 12 gender- and age-matched healthy subjects responded via emails to one of 3 choices: no tooth contact, tooth contact during oral functions or tooth contact not associated with oral functions. The influence of subjective stress, anxiety, depression, personality and daily activities on tooth contact was then assessed. The frequency of the non-functional tooth contact was significantly higher in the patients with TMD than in the healthy subjects (35·0% vs. 9·6%, P < 0·001), while no significant group difference was found for the frequency of functional tooth contact, the stress, anxiety, depression and personality.

Abstract
Obesity and type 2 diabetes (T2D) are characterized by decreased insulin sensitivity and higher concentrations of free fatty acids (FFAs) in plasma. Among FFAs, saturated fatty acids (SFAs), such as palmitate, have been proposed to promote inflammatory responses. Primary Sjögren's syndrome (SS) is an autoimmune disease characterized by inflammatory mononuclear cell infiltration and destruction of epithelial cells in the salivary and lacrimal glands. IL-6 production and α-fodrin degradation are increased in salivary gland epithelial cells of patients with primary SS. Although previous studies have shown a link between SS and either dyslipidemia or T2D, little is known about the clinical significance of FFAs in primary SS. Here we report that SFAs, but not unsaturated fatty acids, induced IL-6 production via NF-κB and p38 MAPK activation in human salivary gland epithelial cells. Moreover, palmitate induced apoptosis and α-fodrin degradation by caspase-3 activation. Unlike salivary gland epithelial cells, induction of IL-6 production and the degradation of α-fodrin in response to palmitate were undetectable in squamous carcinoma cells and keratinocytes. Taken together, SFAs induced IL-6 production and α-fodrin degradation in salivary gland epithelial cells, implicating a potential link between the pathogenesis of primary SS and SFAs level in plasma.

Abstract
The expression of nm23-H1, product of putative metastasis suppressor gene, was evaluated immunohistochemically in 31 cases of adenoid cystic carcinoma (ACC) of salivary glands and correlated with their clinicopathologic features. All benign salivary gland tumors of various types, which were used as a non-metastatic control, showed obvious nm23-H1 expression. The immunoreactivity of tumor cells was stronger than that of normal salivary gland components, although the distribution patterns of positive cells considerably varied between tumor types. In ACC, 16 cases (52%) showed the reduction of nm23-H1 immunoreactivity either in positive cell frequency or staining intensity. These cases were referred to as negative cases. The incidence of negative cases was 67% (10/15) and 38% (6/16) of the cases with and without metastasis, respectively. Furthermore, metastatic tumors showed decreased immunoreactivity of this protein compared with their primary tumors. The prognosis of patients with a nm23 negative tumor was generally poorer than that with a positive tumor. These results may suggest that the reduction of nm23-H1 protein has an implication for metastasis of ACC.

Abstract
BACKGROUND AND PURPOSE The relationship between the MR imaging features and clinical outcomes in patients with hypoglycemic encephalopathy has always been evaluated retrospectively. The aim of this study was to prospectively evaluate whether MR imaging features of patients presenting with hypoglycemic coma are predictive of short-term (1-week) outcomes. MATERIALS AND METHODS Subjects were 36 consecutive patients with hypoglycemia who were in a comatose state on arrival at our hospital from April 2006 to March 2010. MR imaging findings on arrival in relation to the patients' clinical course after glucose infusion were evaluated. RESULTS Thirteen of the 36 patients showed no MR imaging abnormalities on arrival. DWI revealed focal lesions involving the internal capsule in 13 patients and lesions involving bilateral hemispheric white matter in 10 patients. After glucose administration, the patients without lesions and patients with focal internal capsule lesions recovered completely within 1 day. However, patients with diffuse white matter lesions did not recover even within 1 week despite glucose administration. There was no statistical difference in the initial blood glucose levels among patients with the various types of MR imaging findings. CONCLUSIONS On early MR imaging, hypoglycemic brain injury may first appear in the internal capsule and then spread into the hemispheric white matter. The absence of a lesion or the presence of a focal internal capsule lesion may suggest a good outcome. However, diffuse hemispheric white matter lesions may indicate a poor 1-week outcome.

Abstract
The activation of renin-angiotensin system contributes to the development of metabolic syndrome and diabetes as well as hypertension. However, it remains undetermined how renin-angiotensin system is implicated in feeding behavior. Here, we show that angiotensin II type 1 (AT(1)) receptor signaling regulates the hypothalamic neurocircuit that is involved in the control of food intake. Compared with wild-type Agtr1a(+/+) mice, AT(1) receptor knock-out (Agtr1a(-/-)) mice were hyperphagic and obese with increased adiposity on an ad libitum diet, whereas Agtr1a(-/-) mice were lean with decreased adiposity on a pair-fed diet. In the hypothalamus, mRNA levels of anorexigenic neuropeptide corticotropin-releasing hormone (Crh) were lower in Agtr1a(-/-) mice than in Agtr1a(+/+) mice both on an ad libitum and pair-fed diet. Furthermore, intracerebroventricular administration of CRH suppressed food intake both in Agtr1a(+/+) and Agtr1a(-/-) mice. In addition, the Crh gene promoter was significantly transactivated via the cAMP-responsive element by angiotensin II stimulation. These results thus demonstrate that central AT(1) receptor signaling plays a homeostatic role in the regulation of food intake by maintaining gene expression of Crh in hypothalamus and suggest a therapeutic potential of central AT(1) receptor blockade in feeding disorders.

Abstract
In 2005, the Medical Treatment and Supervision (MTS) Act was enacted in Japan to hospitalize the criminally insane and to promote a self-supporting lifestyle after deinstitutionalization. As of October 2010, 490 patients remain hospitalized in 23 highly secure forensic hospitals. Most patients are diagnosed with chronic schizophrenia and exhibit symptoms of drug resistance. Battering is the most common criminal act they have committed.The increased prevalence of the combination of criminal insanity with drug dependence is a common problem in other countries as well. It is a serious problem that diversity in prison medical care has not been achieved.A characteristic feature of care for criminally insane patients in Japan is that they must live in a residential district where a public health center is located and close to forensic hospitals after deinstitutionalization. Although there may be concerns about social prejudice against psychiatric disorders, this limited area would help support rehabilitation of patients because medical staff can easily know the whereabouts, psychiatric condition and aspects, of daily life for each patient through frequent reports obtained from home-visiting nurses. As a result, patients who have been successfully deinstitutionalized lead a self-supporting lifestyle without treatment interruption or repetition of similar criminal acts.In this presentation, we will show the current status of forensic care in Japan, analyze its characteristics and problems described above, and make suggestions for the treatment of the criminally insane in countries with a small national land area such as Japan.

Abstract
The deposition of amyloid β protein (Aβ) is a consistent pathological hallmark of Alzheimer's disease (AD) brains. Therefore, inhibition of Aβ aggregation in the brain is an attractive therapeutic and preventive strategy in the development of disease-modifying drugs for AD. An in vitro study demonstrated that yokukansan (YKS), a traditional Japanese medicine, inhibited Aβ aggregation in a concentration-dependent manner. An in vivo study demonstrated that YKS and Uncaria hook (UH), a constituent of YKS, prevented the accumulation of cerebral Aβ. YKS also improved the memory disturbance and abnormal social interaction such as increased aggressive behavior and decreased social behavior in amyloid precursor protein transgenic mice. These results suggest that YKS is likely to be a potent and novel therapeutic agent to prevent and/or treat AD, and that this may be attributed to UH.

Abstract
Workshops are an important part of the IFPA annual meeting. At IFPA Meeting 2010 diverse topics were discussed in twelve themed workshops, six of which are summarized in this report. 1. The placental pathology workshop focused on clinical correlates of placenta accreta/percreta. 2. Mechanisms of regulation of trophoblast invasion and spiral artery remodeling were discussed in the trophoblast invasion workshop. 3. The fetal sex and intrauterine stress workshop explored recent work on placental sex differences and discussed them in the context of whether boys live dangerously in the womb.4. The workshop on parasites addressed inflammatory responses as a sign of interaction between placental tissue and parasites. 5. The decidua and embryonic/fetal loss workshop focused on key regulatory mediators in the decidua, embryo and fetus and how alterations in expression may contribute to different diseases and adverse conditions of pregnancy. 6. The trophoblast differentiation and syncytialisation workshop addressed the regulation of villous cytotrophoblast differentiation and how variations may lead to placental dysfunction and pregnancy complications.
