Abstract
BACKGROUND Considering concerns about conventional toe grip strength, we devised a method to measure toe pressure strength in the standing position, which is close to the actual motion. This study examined the association between toe pressure strength in the standing position and walking speed among older adults. METHODS This cross-sectional study included 150 community-dwelling older adults (81±8 years, 73% female) who participated in the physical fitness test. We analyzed the correlation between the participants' maximum walking speed and physical function. Furthermore, we performed regression analysis with the maximum walking speed as the dependent variable to examine the association with toe pressure strength in the standing position. We also examined the association between maximum walking speed and toe pressure strength in the standing position by introducing a covariate. RESULTS Correlation analysis revealed a significant positive correlation between maximum walking speed and toe pressure strength in the standing position, with a moderate effect size (r=0.48, p<0.001). Moreover, multiple regression analysis with covariates showed an association between maximum walking speed and toe pressure strength in the standing position (standardization factor=0.13, p<0.026). CONCLUSION Toe pressure strength in the standing position was associated with maximum walking speed. This finding clarifies the significance of assessing toe pressure strength in the standing position and suggests that enhanced toe pressure strength in the standing position may increase maximum walking speed.

Abstract
Background and Objectives Advancing age might impair real-world navigation ability. The use of mobile devices by older adults has grown rapidly in recent years. Navigation applications (apps) in mobile devices may facilitate the freedom of outings for older adults. Our aim is to investigate age-related differences in real-world app-based navigation walking in terms of accuracy, efficiency, and gaze behavior; and to explore clinical factors associated with navigation walking in older adults. Research Design and Methods A total of 20 community-dwelling older adults and 16 young adults completed a route navigation task using a navigation app while recording their gaze behavior. Outcomes were compared in both groups and a general linear regression was used to explore clinical factors associated with app-based navigation walk in older adults. Results Compared with young participants, older participants had more stops and root errors and less fixation time, smaller amplitude of saccades. Additionally, older adults were more likely to glance at their smartphones while app-based navigation walking. Furthermore, gait speed and the following assessment scores were significantly associated with navigation walking in older adults: Mini-Mental State Examination, Life-Space Assessment, and the short version of the Mobile Device Proficiency Questionnaire. Discussion and Implications For app-based navigation walks, differences in accuracy and gaze behavior were found to exist with age. Additionally, efficient real-world navigation walks in older adults require the extent of life space and proficiency with mobile devices, along with walking speed and cognitive function. It is possible that age-related functional decline, such as the visual field and shifting attention between mobile devices and the real world, may have influenced the results. The study also suggests the need to understand the level of proficiency with mobile devices so that older adults can continue to go out freely. These findings give the basis for providing older adults with appropriate navigation assistance.

Abstract
The High energy Engineering X-ray (HEX) diffraction beamline at the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Lab (BNL) is the first high-energy beamline capable of reaching 200 keV for a monochromatic beam. With the 3 GeV electron beam energy for the NSLS-II ring, only the superconducting wiggler (SCW) producing greater than 4 T peak field can cover these ranges with a sufficient number of photons. The 1.2 m-long HEX-SCW has a period length of 70 mm and a field strength on-axis of 4.3 T. It utilizes no liquid helium, and the vertical aperture size of the electron beam vacuum chamber is 8 mm. Unlike regular undulators/wigglers, there is no standard configuration for the magnetic measurement system for superconducting insertion devices. The NSLS-II Insertion Devices group has developed, in collaboration with the vacuum group, a novel in-vacuum Hall mapper with a 1.75 m in-vacuum linear motor and an in-vacuum flip coil system utilizing many commercial-off-the-shelf products. The measurements were conducted at the BNL, and the device was installed in the ring and commissioned. This paper provides a description of the SCW and its magnetic measurement systems, as well as a brief account of the installation and commissioning efforts.

Abstract
BACKGROUND A method has been developed to assess toe pressure strength in the standing position, taking into account concerns about toe grip strength. RESEARCH QUESTION Which is more associated to postural control capability, the conventional toe grip strength or the newly devised toe pressure strength in the standing position, which is close to the actual movement? METHODS This study is a cross-sectional study. This study included 67 healthy adults (mean age, 19 ± 1 years; 64% male). The postural control capability was measured using the center-of-pressure shift distance in the anterior-posterior axis. Toe pressure strength in the standing position was assessed using a toe pressure measuring device to evaluate the force of pressure on the floor surface by all toes. During measurement, care is taken to ensure that the toes do not flex. However, toe grip strength in the sitting position was measured using muscle strength for toe flexion in a conventional manner. Statistical analysis was conducted by performing a correlation analysis between each of the measured items. Additionally, multiple regression analysis was used to examine the functions associated with postural control capability. RESULT Pearson's correlation analysis revealed that the postural control capability was correlated with toe pressure strength in the standing position (r = 0.36, p = 0.003). Multiple regression analysis demonstrated that only toe pressure strength in the standing position was significantly associated with the postural control capability, even after adjusting for covariates (standard regression coefficient: 0.42, p = 0.005). SIGNIFICANCE The results of this study indicated that toe pressure strength in the standing position was more strongly associated with the postural control capability in healthy adults than toe grip strength in the sitting position. It has been suggested that a rehabilitation program for toe pressure strength in the standing position would help improve postural control capability.

Abstract
Evidence suggests that optimism has a positive impact on health status. Attentional bias modification (ABM) may be beneficial for enhancing optimism, but its effective application requires a detailed investigation of the association between attentional bias and optimism. This study aimed to determine the association between attentional bias and optimism based on different task types. Eighty-four participants completed the attentional bias measures using the dot-probe task (DPT), emotional visual search task (EVST) paradigms, and psychological assessments. Optimism was assessed using the Life Orientation Test-Revised with subscales for optimism and pessimism. Pearson's correlation coefficient and multivariate linear regression analysis were applied to investigate the association between optimism and attentional bias. Neither the attentional bias derived from DPT nor EVST was significantly correlated with optimism total score or subscales. Regression analysis also showed no association between attentional bias and optimism (DPT, β = 0.12; EVST, β = 0.09), optimism subscales (DPT, β = 0.09; EVST, β = 0.17), or pessimism subscales (DPT, β = -0.10; EVST, β = 0.02). Our findings showed no evidence that attentional biases derived from either the DPT or EVST measures are associated with optimism or pessimism. Further studies are needed to effectively adapt the ABM to enhance optimism.

Abstract
BACKGROUND It has been shown that involvement in religious activities has a positive impact on psychological aspects. In this study, the relationship between grave visitation, a standard religious activity in Japan, and depression and apathy symptoms was investigated among older adults in Japan. METHODS A total of 638 older adults who participated in a community-based health check survey (Tarumizu Study 2019) were interviewed regarding the presence or absence of grave visitation, frequency, travel time, means of transportation, and flower offerings. Apathy and depressive symptoms were measured using the 15-item Geriatric Depression Scale (GDS-15). The participants were categorised into three grave visitation groups, namely, frequent (more than once per week), occasional (less than once per week), and non-visiting. Outcomes were compared between the frequency groups, and Poisson regression analysis was used to investigate the relationship between grave visitation frequency and apathy and depression. RESULTS Of the participants, 91.8% reported regular grave visitation. The non-visiting group had a significantly higher prevalence of apathy symptoms (44.2%) than the visiting groups. Furthermore, using the frequent group as the reference, Poisson regression analysis adjusted for potential covariates demonstrated that no grave visitation was significantly related to apathy (prevalence ratio, 1.43; 95% confidence interval, 1.00-2.05, P = 0.049). CONCLUSIONS Not practising grave visitation was significantly related to apathy among older adults. Helping older adults to visit graves may prevent apathy by facilitating motivation and increasing activity.

Abstract
Patients with heart disease are more likely to experience social frailty due to physical inactivity, which may affect meaningful activities such as hobbies. This study aimed to investigate (1) the association between heart disease and social frailty in community-dwelling older adults and (2) the characteristics of meaningful activities in community-dwelling older adults with heart disease. Data from 630 older adults who participated in a community-based health survey were obtained, including clinical history, meaningful activities, social frailty and psychosomatic functions. Participants were divided into two groups: those with heart disease (n = 79) and those without (n = 551), and comparisons were made. Social frailty was observed in 23.7% of participants with heart disease, and logistic regression revealed significant associations with heart disease and social frailty after adjusting for potential covariates (OR, 1.97; 95% CI, 1.06 3.67; p = 0.032). Participants with heart disease did not differ significantly in terms of satisfaction or performance; their frequency of engagement in meaningful activities was significantly lower than without heart disease (p = 0.041). These results suggest that heart disease and social frailty are associated in community-dwelling older adults, and that this demographic is inclined to engage in meaningful activities less frequently.

Abstract
BACKGROUND Frailty is a multidimensional condition characterised by reduced physical and psychological resilience. Older adults also frequently demonstrate apathy, suggesting that it shares similar neuro-physiological pathways with frailty. This cross-sectional study aimed to investigate the association between apathy and frailty as defined by a comprehensive assessment. METHODS We analyzed 882 older adults (mean age: 74.4 ± 6.4 years; 62.1% female) who participated in a community-based health check survey (Tarumizu Study). Apathy was measured by the Geriatric Depression Scale-3A, a three-item subset of the Geriatric Depression Scale-15, and frailty by the Kihon Checklist of physical, psychological, functional, and social status. Associations were examined by multinomial logistic regression with frailty status (robust, pre-frailty, frailty) as the dependent variable, apathy as the independent variable, and sociodemographic factors, medications, cognitive function, functional capacity, and mood symptoms as potential confounders. RESULTS Apathy was observed in 23.7% of individuals, and logistic regression revealed significant associations with both pre-frailty and frailty after confounder adjustment (pre-frailty: odds ratio (OR) 1.80, 95% CI 1.22-2.64; frailty: OR 3.24, 95% CI 1.63-6.42). Participants with apathy also exhibited greater deficits in the Kihon Checklist subdomains instrumental activities of daily living (P = 0.022), physical function (P < 0.001), oral function (P < 0.001), and cognitive function (P = 0.001). CONCLUSIONS Our findings underscore the importance of comprehensive frailty assessment and demonstrate that apathy can have pervasive deleterious effects on geriatric health.

Abstract
Background: The psychological condition and frequency of going out (FGO) of community-dwelling older adults after the spread of COVID-19 will provide insights for supporting the daily lives of community-dwelling older adults. Going out is defined as moving from one’s own home to a place or region beyond one’s own home and is considered to reflect the daily and social life of community-dwelling older adults. This study investigates the relationship between the FGO and current psychological condition after the second wave of COVID-19 in community-dwelling older adults in Japan. Methods: This study adopted a self-administered questionnaire by mail. A total of 493 members of CO-OP Kagoshima were included in the analysis and divided into two groups according to the change in FGO. Multiple logistic regression analysis was conducted after a bivariate analysis to investigate the relationship between the FGO and psychological condition. Results: Significant differences were noted between the groups with decreased FGO and those with increased/unchanged FGO in general and pandemic-related psychological condition. Multiple logistic regression analysis showed a significant relationship between FGO and psychological condition, such as mental fatigue, not smiling as much as before, and anxiousness to go outside. Conclusion: Community-dwelling older adults may have experienced a decrease in the frequency of going out and a detrimental effect on their psychological condition after the COVID-19 pandemic. This finding may inform strategies to identify priorities for psychological approaches altered by COVID-19 to prevent confinement and stress in older adults.

Abstract
Objectives This study investigates and describes the time course of fears and worries about COVID-19 among current employees during this outbreak. Study design This was a longitudinal study. Methods This study was a part of the Employee Cohort Study in Japan. The study comprised 4120 individuals from February 2019. A baseline survey in March 2020, a 2-month follow-up survey in May 2020, and a 5-month follow-up survey in August 2020 were conducted. Questions surveyed respondents’ global fear and worry and six items related to COVID-19. A mixed model for repeated measures of an analysis of variance was used. Results A total of 1421 respondents completed the baseline survey. At 2- and 5-month follow-ups, 1032 and 1181 respondents completed surveys, respectively. Of those, 64 and 33 individuals who were temporarily laid off or on leave were recorded as missing values. Global fear and worry about COVID-19 significantly increased from March to August 2020. Fears of personal or family infection, limiting one's activities and national and local government policies also significantly increased with time. In contrast, fears of lack of knowledge and difficulty of obtaining hygiene products significantly decreased. Conclusion To conduct efficient risk communication during a pandemic, knowing the concerns of the populace, providing correct information and a sufficient supply of products, and setting clear guidelines are essential.

Abstract
INTRODUCTION/OBJECTIVES In humans with impaired right-sided cardiac function, the caudal vena cava (CVC) diameter serves as a marker of venous congestion. This study aimed to investigate whether ultrasonographic CVC variables could identify the presence of right-sided congestive heart failure (R-CHF) in dogs with right-sided heart disease (RHD). ANIMALS Fifty client-owned control dogs and 67 dogs with RHD were enrolled. The dogs with RHD were subdivided into the non-R-CHF (n = 43) and R-CHF (n = 24) groups. MATERIALS AND METHODS We measured and compared the ultrasonographic CVC variables and echocardiographic variables among the groups. Receiver operating characteristic (ROC) curve analysis was performed to calculate the sensitivity and specificity of the variables at optimal cutoff values. RESULTS We obtained the highest accuracies of the ratio of the shortest diameter (SD) of the minimal CVC area to the aorta diameter (Ao) during inspiration [SD(min)/Ao] and of the ratio of SD(min) to the longest diameter of the minimal CVC area during inspiration [LD(min),SD/LD(min)], with high sensitivities, specificities, and an area under the ROC curve greater than 0.925. CONCLUSIONS In addition to the echocardiographic assessment of right-sided cardiac function, the CVC variables in this study, especially SD(min)/Ao and SD/LD(min), would be useful diagnostic indices for identifying R-CHF in dogs with RHD.

Abstract
Fluorescence-activated cell sorting (FACS) is a powerful tool for analyzing stem cells. When using fixed cells, however, it is sometimes difficult to analyze RNA extracted from sorted cells due to RNA degradation. We established a protocol for immunocytochemistry before FACS to prevent RNA degradation. Cells were fixed with a methanol-based fixative (UM-Fix), then subjected to immunocytochemistry. The addition of RNase inhibitor and dithiothreitol (DTT) to some buffers used for immunocytochemistry increased RNA integrity after cell recovery. We found increased copy numbers of mRNA in recovered cells using quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis. When RNase inhibitor and DTT were added, amplification of mRNA using T7 promoter was possible with RNA extracted from recovered cells after FACS. Our protocol ensures high quality RNA in cells recovered by FACS; therefore, gene expression analysis with a smaller number of cells is possible using pre-amplification of mRNAs. Our protocol for immunocytochemistry also might be applicable to RNA recovery after immunostaining.

Abstract
A 7-month-old female Japanese Black calf developed elongated, nodular mass measuring 30 × 16 cm extended from the retropharyngeal region to mid lateral neck region. Histological examination revealed granulomatous lymphangitis with non-septate fungal hyphae recognized throughout the lesions. Fungal culture, DNA sequencing and molecular phylogenetic tree analysis confirmed the sequence of Lichtheimia corymbifera. The lymphogenous route was speculated to be the main route of fungal spread leading to the characteristic nodular appearance of this case.

Abstract
The current report aimed to characterize plasma anti-Müllerian hormone (AMH) in bovine male pseudohermaphroditism. The blood AMH concentration in a Japanese Black male pseudohermaphrodite calf was compared with pre- and post-pubertal male and female calves and castrated calves. The concentration in the case was higher than in post-pubertal males, castrated males, and pre- and post-pubertal female calves (p < .05), but similar to that in pre-pubertal male calves. After extraction of the testes, the concentration in the case dropped to a certain extent. The extracted testes expressed AMH, as detected by immunohistochemistry. This study is the first to show the characterization of AMH in a male pseudohermaphrodite calf. AMH levels in peripheral blood might be useful to diagnose male pseudohermaphroditism in cattle.

Abstract
BACKGROUND AND OBJECTIVES Allergic transfusion reactions (ATRs) and febrile non-haemolytic transfusion reactions (FNHTRs) are the two major types of transfusion-related adverse reactions (TRARs). Although prestorage leucocyte reduction and diversion of the first aliquot of blood (LR/D) could reduce FNHTRs and bacterial contamination in adult transfusion, ATRs are still problematic. In addition, there is little information about TRARs in paediatric population. MATERIALS AND METHODS We conducted a single-centre retrospective analysis of all transfusions, except washing products, and TRARs for 153 months to evaluate related factors such as delivery of treatment and the characteristics of recipients. RESULTS Most TRARs were FNHTRs and/or ATRs in children. In delivering blood products with LR/D, the frequencies of not only FNHTRs but also ATRs were significantly reduced with both platelet concentrates (PCs) and red cell concentrates (RCCs). TRARs of fresh-frozen plasma were infrequent in children. In addition, even after the introduction of LR/D, ATRs were significantly more frequent in patients with primary haematological and malignant diseases who received PCs and RCCs, older patients who received PCs and patients who received frequent RCCs. CONCLUSION These results suggest that leucocytes or mediators from leucocytes are underlying cause of ATRs in addition to FNHTRs in children. Furthermore, particular characteristics of patients would be other risk factors for ATRs.

Abstract
A 14-month-old Japanese Black heifer was evaluated on Day 0 (D 0) for enlargement of the right ovary (RO). Transrectal ultrasonography (TRUS) revealed that the RO was markedly enlarged and multicystic, while the left ovary (LO) was small and inactive. The presumptive diagnosis was granulosa-theca cell tumour (GTCT), which was confirmed by markedly elevated plasma anti-Müllerian hormone (AMH) of 4.42 ng/ml. Therefore, ovariectomy of the RO was the treatment of choice. The heifer was checked by TRUS and blood sampling on D 42, D 63 and immediately before ovariectomy on D 85. On D 42, TRUS did not show marked changes in either ovary in comparison with D 0. However, on D 63, the RO had transformed into a single cyst, and on D 85, the LO had resumed cyclic activity. The RO was extracted on D 85 by hand-assisted laparoscopic ovariectomy to allow better control. Unexpectedly, histopathology revealed the lesion to be a fluid-filled cystic structure, with no neoplastic proliferation of follicular epithelium that would indicate GTCT. The wall of the cystic structure consisted of collagen fibres and a few degenerated granulosa cells. The retrospective hormonal analysis revealed that the AMH concentrations had markedly dropped on D 63 and 85, which coincided with resumption of cyclicity in the LO. These findings suggest that the GTCT had self-cured and transformed into a cyst-like structure. The heifer then received an oestrous synchronization regime on D 105, was artificially inseminated on D 115 and became pregnant.

Abstract
It is important to search the biomarker to predict the development and prognosis of autoimmune thyroid diseases (AITDs) such as Hashimoto's disease (HD) and Graves' disease (GD). MicroRNA (miR) bind directly to the 3' untranslated region of specific target mRNAs to suppress the expression of proteins, promote the degradation of target mRNAs and regulate immune response. miR-125a is known to be a negative regulator of regulated upon activation normal T cell expressed and secreted (RANTES), interleukin (IL)-6 and transforming growth factor (TGF)-β; however, its association with AITDs remains unknown. To clarify the association between AITDs and miR-125a, we genotyped the rs12976445 C/T, rs10404453 A/G and rs12975333 G/T polymorphisms in the MIR125A gene, which encodes miR-125a, using direct sequencing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods in 155 patients with GD, 151 patients with HD and 118 healthy volunteers. We also examined the expression of miR-125a in peripheral blood mononuclear cells (PBMCs) from 55 patients with GD, 79 patients with HD and 38 healthy volunteers using quantitative real-time PCR methods. We determined that the CC genotype and C allele of the rs12976445 C/T polymorphism were significantly more frequent in patients with HD compared with control subjects (P < 0·05) and in intractable GD compared with GD in remission (P < 0·05). The expression of miR-125a was correlated negatively with age (P = 0·0010) and down-regulated in patients with GD compared with control subjects (P = 0.0249). In conclusion, miR-125a expression in PBMCs and the rs12976445 C/T polymorphism were associated with AITD development and prognosis.

Abstract
Vitamin D is a multi-functional immune regulator, and a low serum concentration of vitamin D promotes autoimmune inflammation. In this study, we evaluate the association between the prognosis of autoimmune thyroid disease (AITD) and the functional polymorphisms of genes that regulate vitamin D metabolism. For 139 Graves' disease (GD) patients, 116 Hashimoto's disease (HD) patients and 76 control subjects, we genotyped the following polymorphisms using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP): vitamin D receptor (VDR): rs731236, rs7975232, rs2228570 and rs1544410; group-specific component (GC): rs7041 and rs4588; and CYP2R1: rs10741657. The frequency of the TT genotype for the rs731236 polymorphism was higher in GD patients than in HD patients (P = 0·0147). The frequency of the C allele for the rs7975232 polymorphism was higher in GD patients than in control subjects (P = 0·0349). The proportion of GD patients whose anti-thyrotrophin receptor antibody (TRAb) level was >51% was higher in those with the CC genotype than in those with the CA+AA genotypes (P = 0·0065). The frequency of the CC genotype for the rs2228570 polymorphism was higher in HD patients than in control subjects (P = 0·0174) and GD patients (P = 0·0149). The frequency of the Gc1Gc1 genotype for the GC polymorphism and the AG genotype for the CYP2R1 polymorphism were lower in intractable GD than in GD in remission (P = 0·0093 and 0·0268, respectively). In conclusion, genetic differences in the VDR gene may be involved in the development of AITD and the activity of GD, whereas the genetic differences in the GC and CYP2R1 genes may be involved with the intractability of GD.

Abstract
Detection and analysis of a small subpopulation of cells such as stem cells or cancer stem cells are recognized to be a key technique in a recent regeneration and cancer science. However, in the thyroid, no marker that identifies stem cells has been established yet. We previously established a novel method to analyze cells collected by fluorescence-activated cell sorting (FACS), named mRNA quantification after FACS (FACS-mQ). By using this method, the biological characteristics of the sorted cells can be determined by analyzing their gene expression profile. In this study, we analyzed the expression of stemness genes in a rat thyroid cell lines FRTL5 using FACS-mQ. 3 stemness genes, NANOG, ABCG2 and GATA4, were expressed in FRTL5. In FRTL5 cells, varied expression of thyroglobulin (TG) among cells was observed by flow cytometry. Cell populations with high or low TG expression were analyzed by FACS-mQ. The cell population with low TG expression showed increased expression of the stemness genes. Furthermore, Ki67-positive cells showed increased expression of TG, which suggested that cells with high TG proliferated rapidly. These results indicated that FRTL5 contains a cell population with high stemness gene expression and less differentiated features, resembling stem cells. These cells might regulate proliferation in FRTL5.

Abstract
To clarify the association between factors regulating DNA methylation and the prognosis of autoimmune thyroid diseases (AITDs), we genotyped single nucleotide polymorphisms in genes encoding DNA methyltransferase 1 (DNMT1), DNMT3A, DNMT3B, methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR), which are enzymes essential for DNA methylation. Subjects for this study included 125 patients with Hashimoto's disease (HD), including 48 patients with severe HD and 49 patients with mild HD; 176 patients with Graves' disease (GD), including 79 patients with intractable GD and 47 patients with GD in remission; and 83 healthy volunteers (control subjects). The DNMT1+32204GG genotype was more frequent in patients with intractable GD than in patients with GD in remission. Genomic DNA showed significantly lower levels of global methylation in individuals with the DNMT1+32204GG genotype than in those with the AA genotype. The MTRR+66AA genotype was observed to be more frequent in patients with severe HD than in those with mild HD. The DNMT1+14395A/G, DNMT3B-579G/T, MTHFR+677C/T and +1298A/C polymorphisms were not correlated with the development or prognosis of AITD. Our study indicates that the DNMT1+32204GG genotype correlates with DNA hypomethylation and with the intractability of GD, and that the MTRR+66AA genotype may correlate with the severity of HD.

Abstract
We developed an in-tube in situ hybridization method for mRNA quantification after fluorescence-activated cell sorting (FACS-mQ). A specific RNA in a particular cell type is stained with a cRNA probe and a fluorescent dye, which allows the stained cells to be selected by FACS without excessive RNA degradation. Our previous protocol required 4 h for hybridization with a cRNA probe, which might not produce enough fluorescence signal for sorting genes with low expressions. We determined the effect of prolonged hybridization for in-tube in situ hybridization on quantitative measurement of intracellular RNAs. During the hybridization step, the quantity of ACTB mRNA decreased gradually until 4 h, but remained constant from 4 to 16 h below 63.6° C. For flow cytometry, cells hybridization with cRNA probes for TG mRNA at 60° C for 16 h showed both increased signal and decreased background fluorescence compared to those hybridized for 4 h. These results indicate that when performing in-tube in situ hybridization, hybridization temperature can be raised to 63.6° C and the hybridization step can be extended up to 16 h without excessive intracellular RNA degradation.

Abstract
We report the first experimental demonstration of a slippage-dominant free-electron laser (FEL) amplifier using a 140-fs full width at half maximum broadband seed laser pulse. The evolution of the longitudinal phase space of a laser seeded FEL amplifier in the slippage-dominant regime was experimentally characterized. We observed, for the first time, that the pulse duration of the FEL is primarily determined by the slippage between the seed laser and the electron beam. With a ± 1% variation in the electron-beam energy, we demonstrated reasonably good longitudinal coherence and a ± 2% spectral tuning range. The experimentally observed temporal and spectral evolution of the slippage-dominant FEL was verified by the numerical simulations.

Abstract
The glucocorticoid-induced tumour necrosis factor (TNF)-receptor (GITR) affects the functions of regulatory T (T(reg)) and effector T (T(eff)) cells, but the significance of this phenomenon is still unclear. To examine the association of single nucleotide polymorphisms (SNPs) in the GITR gene with the expression of GITR molecules on T cells and with the pathological conditions in patients with autoimmune thyroid disease (AITD), we examined the frequencies of four candidate SNPs in AITD patients and healthy volunteers by restriction enzyme analysis and direct sequence analyses. We also analysed the GITR expression on peripheral T(reg) and T(eff) cells in AITD patients by three-colour flow cytometry. The CC genotype in the rs3753348 C/G SNP was significantly more frequent in patients with mild Hashimoto's disease (HD) than in those with severe HD [P = 0·0117, odds ratio (OR) = 3·13]. The AA genotype in the rs2298213 A/G SNP was significantly more frequent in patients with mild HD than in patients with severe HD (P = 0·010, OR = 4·43). All patients and healthy individuals had the GG genotype in rs60038293 A/G and rs11466696 A/G SNPs. The proportions of GITR(+) cells in T(reg) and T(eff) cells were significantly higher in AITD patients with the CC genotype of the rs3753348 SNP than in those with the GG genotype (P = 0·004 and P = 0·011, respectively). In conclusion, the rs3753348 C/G SNP in the GITR is associated with HD prognosis and expression on T(reg) and T(eff) cells.

Abstract
To clarify the association of genetic producibility of interleukin (IL)-5, IL-6 and IL-13, which are secreted by T helper type 2 (Th2), with the development and prognosis of autoimmune thyroid disease (AITD), we genotyped IL5-746C/T, IL6-572C/G and IL13-1112C/T polymorphisms, which are functional polymorphisms in the promoter regions of the genes regulating these cytokines. Fifty-seven patients with intractable Graves' disease (GD), 52 with GD in remission, 52 with severe Hashimoto's disease (HD), 56 with mild HD and 91 healthy controls were examined in this study. The IL13-1112T allele, which correlates with higher producibility of IL-13, was more frequent in patients with GD in remission than in those with intractable GD [P=0·009, odds ratio (OR)=3·52]. The IL5-746T allele, which may correlate with lower levels of IL-5, was more frequent in patients with GD in remission than controls (P=0·029, OR=2·00). The IL6-572G allele carriers (CG and GG genotypes), which have higher producibility of IL-6, were more frequent in AITD patients (P=0·033, OR=1·75), especially in GD in remission (P=0·031, OR=2·16) and severe HD (P=0·031, OR=2·16) than in controls. Interestingly, both allele and genotype frequencies of Th2 cytokine genes were similar between GD and HD patients. In conclusion, functional polymorphisms in the genes encoding Th2 cytokines are associated differently with the development and prognosis of AITD from each other.

Abstract
The severity of Hashimoto's disease (HD) and intractability (or inducibility to remission) of Graves' disease (GD) varies among patients. Forkhead box P3 (FoxP3) is a crucial regulatory factor for the development and function of regulatory T (T(reg) ) cells, and deficiency of the FoxP3 gene (FOXP3) suppresses the regulatory function of T(reg) cells. To clarify the association of the functional polymorphisms of the FOXP3 with the prognosis of GD and HD, we genotyped -3499A/G, -3279C/A and -2383C/T polymorphisms in FOXP3 gene obtained from 38 patients with severe HD, 40 patients with mild HD, 65 patients with intractable GD, in whom remission was difficult to induce, 44 patients with GD in remission and 71 healthy volunteers. The -3279CA genotype was more frequent in patients with GD in remission than in patients with intractable GD, and the -3279AA genotype, which correlates to defective transcription of FOXP3, was absent in patients with GD in remission. The -2383CC genotype was more frequent in patients with severe HD than in those with mild HD. In conclusion, the -3279A/C polymorphism is related to the development and intractability of GD and the -2383CC genotype to the severity of HD.

Abstract
Gelatinous transformation of the bone marrow is a rare disease characterised by a focal marrow hypoplasia, fat atrophy and accumulation of extracellular mucopolysaccharides abundant in hyaluronic acid, which is often associated with extreme malnutrition and weight loss. There are only two reports describing its association with systemic lupus erythematosus (SLE). One described underlying diseases in 155 cases of gelatinous transformation of the bone marrow and found one case with clinical diagnosis of SLE, but no clinical details were provided. The other described three SLE patients with gelatinous transformation of the bone marrow; however, two of these were cachectic and one was diagnosed with concomitant tuberculosis. We describe one active SLE patient without other comorbidities whose pancytopaenia was histologically confirmed as gelatinous transformation. The combination of high-dose steroid, intravenous immunoglobulin and mycophenolate mofetil improved the peripheral blood cytopaenia and reversed the bone marrow abnormalities.

Abstract
Coarctation of the aorta is rare. We present a case of atypical coarctation due to aortitis syndrome with congestive heart failure refractory to conventional medical treatment. Although indications for surgical treatment are not well established and, in general, treatment of choice is an aorto-aortic bypass, we selected axillo-iliac bypass with subcutaneous tunnel because of severe heart failure. Postoperatively, the pressure gradient disappeared and heart failure was improved.

Abstract
Tensin3 is a member of tensin family which is localized in focal adhesion. In our previous study, a high level of tensin3 mRNA expression was observed in the thyroid but not in other tissues, thus, tensin3 gene was regarded as a novel thyroid-specific gene. The high expression level of tensin3 mRNA in normal thyroid tissue suggests some fundamental roles in thyroid functions. In fact, the expression level of tensin3 mRNA was low in most thyroid carcinomas and non-functioning thyroid follicular adenomas which do not produce thyroid hormone. In the present study, we measured the expression levels of tensin3 mRNA in twelve functional adenomas and compared the results with those in normal thyroid tissues, adenomatous goiters and non-functioning thyroid follicular adenomas. Tensin3 mRNA was expressed abundantly in all twelve functional adenomas at almost the same level as in normal thyroid tissues and adenomatous goiters, while its expression was significantly lower in non-functioning follicular adenomas. Considering these facts, an abundant expression of tensin3 mRNA is observed in tissues that produce thyroid hormone, which suggests some fundamental roles in basic thyroid functions.

Abstract
OBJECTIVE To investigate the rates of attempted suicide and its association with psychological distress, experiences of bullying and verbal harassment, and demographic characteristics among Japanese homosexual, bisexual or other men questioning their sexual orientation. DESIGN A cross-sectional design using Japanese participants recruited through the internet. RESULTS Of the 1025 respondents, 154 (15%) of the men reported a history of attempted suicide, 716 (70%) showed high levels of anxiety and 133 (13%) showed high levels of depression. 851 (83%) experienced school bullying and 615 (60%) were verbally harassed because of being perceived by others as homosexual. Independent correlates of attempted suicide were psychological distress, history of being verbally harassed, history of sex with a woman, history of meeting a male through the internet, disclosing sexual orientation to six or more friends and not having a university degree. CONCLUSIONS Mental health services and prevention programmes are needed to deal with the psychological consequences of social stigma for Japanese men who are homosexual, bisexual or questioning their sexual orientation.

Abstract
OBJECTIVE To provide an overview of thyroid abnormalities that can occur after delivery. METHODS We review the diagnosis and management of various types of postpartum thyroid dysfunction. RESULTS A common problem during the postpartum period, thyroid dysfunction is found in approximately 5% of new mothers in the general population. Such thyroid dysfunction can manifest in various forms (hyperthyroid or hypothyroid, transient or persistent), each of which necessitates different treatment. The most common type of thyroid dysfunction is destructive thyrotoxicosis, which is due to the aggravation of autoimmune thyroiditis. It occurs at 1 to 3 months after delivery as sudden thyrotoxicosis and lasts for 1 to 3 months, after which transient hypothyroidism may ensue in some cases. Simply symptomatic treatment may be sufficient for such transient thyroid dysfunctions. Postpartum Graves' disease is found in approximately 11% of the cases of postpartum thyroid dysfunction. Graves' hyperthyroidism usually occurs at 3 to 6 months after parturition. In the treatment of postpartum Graves' disease, one may choose radioactive iodine, antithyroid drugs, or surgical therapy; however, transient Graves' hyperthyroidism, which often occurs in patients with postpartum Graves' disease, may require neither radioactive iodine therapy nor thyroidectomy. Mothers at high risk for development of postpartum thyroid dysfunction can be screened by testing for antimicrosomal antibodies. Although a strong correlation exists between the presence of antimicrosomal antibodies and postpartum thyroid dysfunction, the cost-effectiveness of screening for postpartum autoimmune thyroid syndrome remains controversial. CONCLUSION For optimal management of the postpartum conditions of Graves' disease, destructive thyrotoxicosis, and hypothyroidism, the clinician should be aware of diagnostic techniques that will facilitate early intervention or will prompt careful surveillance.

Abstract
Arthrobacter globiformis T6 is unique in that it produces an enzyme yielding only isomaltose from dextran. In the present study, the organism was re-identified and its classification as a new species of the genus Arthrobacter, A. dextranlyticum, was proposed. The high G+C gene (66.8 mol%) for the isomalto-dextranase was sequenced. The deduced amino acid sequence, with a calculated molecular mass of 65,993 Da (603 amino acids), was confirmed by nanoscale capillary liquid chromatography coupled to tandem mass spectrometry, which covered 71.1% of the amino acid residues of the entire sequence. The enzyme was grouped into glycoside hydrolase family 27, and the C-terminal domain has homology to carbohydrate-binding module family 6. Hyper-exoproduction of the recombinant enzyme was achieved at a level corresponding to approximately 4.6 g l(-1) of culture broth when proteases-deficient Bacillus subtilis cells were used as the host. The purified enzyme (65.5 kDa) had an optimal pH and temperature for activity of 3.5 and 60 degrees C, respectively. It was crystallized using the sitting-drop vapor-diffusion method at 293 K.

Abstract
An agar-degrading bacterium, strain JAMB-A7, was isolated from the sediment in Sagami Bay, Japan, at a depth of 1,174 m and identified as a novel species of the genus Microbulbifer. The gene for a novel beta-agarase from the isolate was cloned and sequenced. It encodes a protein of 441 amino acids with a calculated molecular mass of 48,989 Da. The deduced amino acid sequence showed similarity to those of known beta-agarases in glycoside hydrolase family 16, with only 34-55% identity. A sequence similar to a carbohydrate-binding module was found in the C-terminal region of the enzyme. The recombinant agarase was hyper-produced extracellularly using Bacillus subtilis as the host, and the enzyme purified to homogeneity had a specific activity of 398 U (mg protein)(-1) at pH 7.0 and 50 degrees C. It was thermostable, with a half-life of 502 min at 50 degrees C. The optimal pH and temperature for activity were around 7 and 50 degrees C, respectively. The pattern of agarose hydrolysis showed that the enzyme was an endo-type beta-agarase, and the final main product was neoagarotetraose. The activity was not inhibited by NaCl, EDTA, and various surfactants at high concentrations. In particular, sodium dodecyl sulfate had no inhibitory effect up to 2%.

Abstract
Autoimmune diseases, especially autoimmune thyroid disease, frequently develop after delivery due to the immune rebound mechanism. Most cases involve transient dysfunction of affected organs. We examined three patients who developed liver dysfunction after delivery. They were all diagnosed with definite or probable autoimmune hepatitis using the scoring system of the International Autoimmune Hepatitis Group. Moreover, all of them had anti-CYP2D6 antibodies detected by a sensitive radioligand assay. Our findings strongly suggest that liver dysfunction is induced by postpartum autoimmune hepatitis, and clinicians should be aware of this disease.

Abstract
We produced experimental autoimmune hypophysitis (EAH) in rats and investigated its characteristics. Female Lewis rats were immunized by two injections with homologous pituitary homogenate and complete Freund's adjuvant. Blood was collected serially from the rats, and serum antibodies to pituitary antigens were examined. The rats were sacrificed 2 or 4 weeks after the final immunization, and histological examinations of the endocrine organs were carried out. Histological examination revealed slight, focal infiltration of mononuclear cells in the pituitary gland only in the rats immunized with the pituitary homogenate. Infiltration of mononuclear cells was not observed in the thyroid gland, pancreas, adrenal gland, or ovary. In the serological examination, antibodies to both cytosolic antigens and cytoplasmic particle antigens from the pituitary gland were detected by enzyme-linked immunosorbent assay (ELISA), and these antibody levels increased with time. Western blotting using the serum antibodies identified an immunoreactive protein of approximately 21.5 kDa among these antigens, and we confirmed that this protein was rat growth hormone (GH). Furthermore, antibodies to GH, thyrotropin (TSH), and luteinizing hormone (LH) were detected by ELISA. Antibodies to follicule stimulating hormone, prolactin, or adrenocorticotropin were not detected. These data suggest that several antigens from the pituitary gland are involved in EAH in rats, and that GH, TSH, and LH are major antigens among the pituitary antigens in this model.
