Abstract
Factors associated with dynamic changes in the objectively measured physical activity have not been well understood. We aimed to 1) evaluate the longitudinal change in the physical activity trajectory according to sex which is associated with age and to 2) determine the factors associated with the dynamic change in physical activity-related variables across a wide age range among Japanese adults. This longitudinal prospective study included 689 Japanese adults (3914 measurements) aged 26-85 years, whose physical activity data in at least two surveys were available. Physical activity-related variables, such as intensity (inactive, light [LPA; 1.5 to 2.9 metabolic equivalents (METs)], moderate-to-vigorous [MVPA; ≥3.0 METs]), total energy expenditure (TEE), physical activity level (PAL), and step count, were evaluated using a validated triaxial accelerometer. Statistical analysis involved the latent growth curve models and random-effect panel data multivariate regression analysis. During a mean follow-up period of 6.8 years, physical activity was assessed an average of 5.1 times in men and 5.9 times in women. The profiles for the inactive time, LPA (only men), MVPA, step count, PAL, and TEE showed clear curvature, indicating an accelerated rate of change around the age of 70. In contrast, other variables exhibited minimal or no curvature over the age span. The MVPA trajectory was positively associated with alcohol consumption, hand grips, leg power, and trunk flexibility and negatively associated with age, local area, body mass index (BMI), comorbidity score, and heart rate over time. Our results indicated that the physical activity trajectory revealed clear curvature, accelerated rate of change around the age of 70, and determined physical health and fitness and BMI as dynamic factors associated with physical activity changes. These findings may be useful to help support populations to achieve and maintain the recommended level of physical activity.

Abstract
Methylthioacetic acid (MTA) is an acid-hydrolyzed derivative of a natural aroma compound, methylthioacetic acid ethyl ester isolated from Cucumis melo var. conomon (Katsura-uri, Japanese Picking Melon), and induces a villiform-like structure dome in RCM-1 human colorectal cancer cell culture. Thus far, the physiological and molecular properties of MTA-mediated dome formation remain unknown. Herein, MTA (not more than 2 mM) was demonstrated to differentiate the unorganized cell mass into the dome in RCM-1 cell culture by disclosing the correlation between dome formation and several intestinal differentiation markers such as alkaline phosphatase activity and the protein levels of dipeptidyl peptidase 4, villin, and Krüppel-like factor 4. Dome formation in RCM-1 cell culture was additively enhanced by the simultaneous administration of MTA and butyric acid (BA), suggesting that MTA directs the differentiation of RCM-1 cells, potentially through the same or similar pathway(s) shared with BA. Notably, a high dose of MTA (2 mM or more) elevated several apoptosis markers, such as DNA fragmentation, caspase-3/7 activity, and cleavage of poly(ADP-ribose) polymerase. Altogether, in addition to RCM-1 cell differentiation, MTA triggers apoptosis. These results indicate that MTA is a potential anticarcinogenic agent applicable in differentiation therapy and traditional chemotherapy against colorectal cancers.

Abstract
BackgroundThe paradigm shift has caused in the treatment for rheumatoid arthritis (RA) before the last decade [1]. The advent of high-dose MTX and biologics has maked it possible to treat RA with early and aggressive therapy, and prevent the joint destruction [2].ObjectivesTo aim of this study, we investigated the joint destruction and clinical outcomes in patients with early RA every 5 years in the last decade.Methods81 patients with early RA (within 1 year from their onset of RA) enrolled retrospectively in this study. The number of patients with early RA were 21 in 2009, 23 in 2014, and 37 in 2019, respectively. They had 17 males and 64 females. Mean age was 59 years (19-92) at the first visit to our department. The following items were investigated: age, disease duration from onset to consultation, anti-cyclic citrullinated peptide antibody (ACPA) positivity (positivity was defined as >4.5 U/ml), CRP, DAS28CRP4, medications, and modified total sharp score (mTSS) at the time of initial consultation and 1 year later. Kruskal-Wallis test was used for statistics (PASW 25 software, SPSS Institute Inc., Chicago, IL, USA, p<0.05).ResultsThe ACPA positivity rates were 71.4% (15/21) in 2009, 78.3% (18/21) in 2014, and 78.4% (29/37) in 2019, respectively. The mean value of DAS28CRP4 was 4.7 (2.4-6.8) in 2009, 4.2 (1.2-6.2) in 2014, and 4.2 (2.1-6.7) in 2019 at the time of the first visit to our department respectively. DAS28CRP4 under 2.6 was 29% (6/21) in 2009, 61% (14/23) in 2014, and 54% (20/37) in 2019 1 year after the first visit. The mean improvement of DAS28CRP4 (ΔDAS28CRP4) was -1.2 (-3.9 - 2.1) in 2009, -1.5 (-4.0 - 1.7) in 2014, and -1.7 (-4.1 - 0.4) in 2019, respectively. It had tended to improve gradually, however, it was not significantly different (p= 0.20, Figure 1).Figure 1.Mean value of improvement of mTSS and DAS28CRP4 (ΔmTSS and ΔDAS28CRP4) from initial visit to 1 year later at 2009, 2014 and 2019.The changing of mTSS for a year (ΔmTSS) was 4.2 (0-17) in 2009, 0.9 (0-10) in 2014, and 0.6 (0-4) in 2019, respectivly. ΔmTSS in 2014 and 2019 was significantly lower compared to that in 2009 (p<0.05, Figure 1).One year after the first visit to our department, the mean dose of MTX increased to 9.2 mg/week (2-14) in 2014 and 8.7 mg/week (4-16) in 2019 compared to 6.6 mg/week (2-8) in 2009 (p=0.19). The mean dose of PSL decreased 4.2 mg/day (1-8) in 2014, and 3.8 mg/day (1-10) in 2019 compared to 4.9 mg/day (2-10) in 2009, respectively (p=0.11). On the other hand, biological DMARDs were introduced in 24% (5/21) in 2009, 13% (3/23) in 2014, and 13% (1/37) in 2019, respectively.ConclusionJonit destruction has been already reported to begin in patients with early-stage of RA [1, 2]. Based on the results of this study, joint desctruction in early RA was decreased in the last decade, because of more early and aggressive therapy for early RA with increasing mean dose of MTX gradually, not biologic DMARDs in real world. In addition, the mean dose of PSL in 2014 and 2019 decreased compared to that in 2009. The intensive therapy for early RA at our hospital has shown the improvement of joint destruction in the last decade.References[1]Emery P, Breedveld FC, Dougados M, et al.

Abstract
BackgroundThe pharmacotherapy for rheumatoid arthritis (RA) has changed dramatically and caused a paradigm shift with the advent of methotrexate (MTX) and biological disease-modifying antirheumatic drugs (bDMARDs).Before the paradigm shift of RA therapy, the frequency of carpal collapse was high in patients with RA.It has been reported that certain numbers of patients with RA rapidly advance the destruction of the carpal bones during the early onset in the natural course of it [1].Another report showed that hand function was positively correlated with disease activity[2]In Japan, bDMARDs were approved in 2003, and the maximum allowable dose of MTX was raised from 8 mg/week to 12 mg/week in 2012.We hypothesize early aggressive therapy for the patients with early RA may have improved outcomes of carpal bone destruction in this last decade.In this study, we investigated the change of drug therapy and carpal height ratio (CHR) in patients with early RA in the last decade.ObjectivesThe aim of this study was to investigate CHR and drugs for the patients with early RA who developed it and started the therapy in 2009, 2014, and 2019.MethodsPatients with early RA diagnosed in our department in 2009, 2014, and 2019 were included in the study.The CHR was measured at the first visit and two years later on radiographs of both hands.The drug history for RA was obtained in the medical records retrospectively.All statistical analyses were performed with EZR version 1.55.ResultsThis study included 43 cases (36 females, 7 males). The number of cases in 2009, 2014, and 2019 was 16, 13, and 14, respectively.The mean age at the time of initial examination was 55 years (30-72).There was no significant difference in the mean value of DAS28-CRP at the time of the first visit in each year.The left hand CHR of initial diagnosis was 0.554 (0.484-0.632), 0.551 (0.490-0.618), and 0.567 (0.517-0.632) in 2009, 2014, and 2019, respectively, with no significant difference.Two years later, the left-hand CHR was 0.541 (0.475-0.651), 0.549 (0.502-0.617), and 0.562 (0.528-0.591), respectively, with no significant difference.There was also no significant difference in the amount of change.The right hand CHR of initial diagnosis was 0.525 (0.475-0.607), 0.539 (0.459-0.589), and 0.557 (0.506-0.635) in 2009, 2014, and 2019, respectively, with no significant difference.Two years later, the right-hand CHR was 0.532 (0.444-0.627), 0.529 (0.478-0.588), and 0.548 (0.491-0.593), respectively, with no significant difference.There was also no significant difference in the amount of change.The DAS28-CRP of initial diagnosis for cases in 2009, 2014, and 2019 was 4.68 (3.11-6.83), 4.19 (1.21-6.15), and 4.23 (2.41-6.38), respectively.The DAS28-CRP at 2 years after treatment for cases in 2009, 2014, and 2019 was 2.12 (0.96-3.60), 2.25 (1.13-4.81), and 2.04 (0.99-3.45), respectively.Although DAS28-CRP was improved, there was no significance among the three groups.The usage rate of MTX was 56.3% in 2009, 76.9% in 2014, and 50% in 2019, with mean doses of 6.2 mg (2-8 mg), 8.6 mg (4-12 mg), and 9.1 mg (4-16 mg), respectively. There was no significant difference in the rate and dosage of MTX use in each year.bDMARDs were used in one case in 2009, two cases in 2014, and one case in 2019.ConclusionIn this study, DAS28-CRP showed a trend of improvement in this decade, but there was no obvious improvement in the progression of carpal collapse.Further early aggressive therapy may be necessary to prevent the destruction of the carpal bones.References[1]Ochi T, Iwase R, Yonemasu K, Matsukawa M, Yoneda M, Yukioka M, et al.

Abstract
Mentha is a complex genus encompassing many species as a consequence of their interspecific hybridization and polyploidy. Southeast Asian mints have been poorly distinguished though they are widely used for culinary and medical purposes. In this study, we have analyzed Southeast Asian mints and known varieties as well as a related Lamiaceae species (Nepeta sp.) using simple sequence repeat (SSR) markers and leaf morphology. Two types of mints were clearly distinguished based on their venation pattern and leaf shape index. We developed 12 SSR markers that allowed good amplification in the Mentha and another Lamiaceae species. In the SSR-based phylogram, the Mentha lines could be delimited into groups I-VI. The Southeast Asian mints divided into groups I and II, and the phylogram separated most of the available species, with groups I and II containing the known species M. × cordifolia and M. arvensis, respectively. The separation of the two groups was supported by a population structure analysis. The SSR markers developed in this study enabled the simultaneous classification of mints and will help improve our understanding of the genetic composition of known mint varieties and as yet unclassified Southeast Asian mints.

Abstract
Background Many cross-sectional studies have identified modifiable factors such as dietary intake, physique, and physical activity associated with diet quality but were unable to determine how a specific individual's diet quality changes with these factors. These relationships may vary depending on an individual's dietary intake. We aimed to determine the association between temporal changes in diet quality and concurrent changes in dietary intake, body mass index (BMI), and physical activity according to the diet quality trajectory pattern. Methods This longitudinal prospective study included 697 Japanese adults aged 26–85 years, at baseline, with available data from at least two dietary intake surveys (4,118 measurements). Dietary intake and physical activity were evaluated using validated dietary questionnaires and a triaxial accelerometer. Diet quality was calculated using the Nutrient-Rich Food Index 9.3 (NRF9.3), while physical activity was calculated based on the duration of activity performed at each level of intensity (sedentary, light, moderate, and vigorous). Body mass index was calculated from the measured height and weight. Statistical analyses involved latent class growth models (LCGM) and random-effect panel data analysis. Results During a mean follow-up period of 6.8 years, NRF9.3 scores were assessed, on average, 5.4 times in men and 6.1 times in women. Based on the NRF9.3 score, three separate trajectory groups—“low-increasing,” “medium-increasing,” and “high-stable”—among individuals aged 26–90 years were identified using LCGM. In the multivariate analysis, the NRF9.3 score trajectory was positively associated with intake of energy, protein, dietary fiber, vitamins A and C, magnesium, and food items, such as fruits and vegetables, and was negatively associated with BMI and the intake of added sugar, saturated fats, sodium, and food items, such as meat and sugar and confectioneries, even after adjusting for covariates. These relationships displayed heterogeneity across the identified NRF9.3 score trajectory groups. In the low-increasing group, an inverse relationship was observed between sedentary behavior and NRF9.3 score trajectory. Conclusions We identified modifiable factors associated with temporal changes in diet quality across a wide age range; however, these factors may vary according to the diet quality trajectories. Our findings may help develop effective strategies for improving diet quality, according to the trajectory of diet quality.

Abstract
Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a low-grade adnexal malignant neoplasm. We report a 90-year-old man who had a hard, dome-shaped tumor approximately 9 mm in diameter on the left cheek. Dermoscopy showed an overall, non-uniformly light-pink tumor with crust. The diagnosis of EMPSGC is made histologically from excisional biopsy. No signs of recurrent disease were evident at 42 months postoperatively.

Abstract
A scabies burrow is created by a mature female mite laying eggs through the stratum corneum, representing a kind of scabies eruption. We have noticed that the edges of the scabies burrow sometime appear as blackish-gray lines. We named these lines the "gray-edged line" sign, as a new feature of scabies burrows. The gray-edged line sign has the following two tendencies: (i) it is rarely seen on the palm or sole; and (ii) when the burrow follows a curved course, the gray-edged line often forms on the outer wall. Explaining the formation of this sign from clinical findings was difficult, so the aim of the present study was to elucidate the mechanisms underlying the gray-edged line sign. This retrospective study involved collection of data from electronic medical records of patients treated for scabies in our department between April 2015 and February 2020. We treated 32 scabies patients, including 4 patients with the gray-edged line sign. We analyzed clinical features, dermoscopy, histopathology and special stains. Fontana-Masson staining showed melanin staining in three parts: feces; some keratinocytes around the scabies burrows; and the mouth and legs of the scabies mite. The gray-edged line sign appears to represent mite feces containing melanin.

Abstract
Colorectal cancer was the third most commonly diagnosed malignant tumor and the fourth leading cause of cancer deaths worldwide in 2012. A human colorectal cancer cell line, RCM‐1, was established from a colon cancer tissue diagnosed as a well‐differentiated rectum adenocarcinoma. RCM‐1 cells spontaneously form ‘domes’ (formerly designated ‘ducts’) resembling villiform structures. Two sulphur‐containing compounds from Cucumis melo var. conomon (Katsura‐uri, or Japanese pickling melon), referred to as 3‐methylthiopropionic acid ethyl ester (MTPE) and methylthioacetic acid ethyl ester (MTAE), can induce the differentiation of the unorganized cell mass of an RCM‐1 human colorectal cancer cell culture into a dome. However, the underlying molecular mechanisms of such dome formation have not been previously reported. Here, we performed a structure–activity relationship analysis, which indicated that methylthioacetic acid (MTA) was the lowest molecular weight compound with the most potent dome‐inducing activity among 37 MTPE and MTAE analogues, and the methylthio group was essential for this activity. According to our microarray analysis, MTA resulted in down‐regulation of 537 genes and up‐regulation of 117 genes. Furthermore, MTA caused down‐regulation of many genes involved in cell‐cycle control, with the cyclin E2 (CCNE2) and cell division cycle 25A (CDC25A) genes being the most significantly reduced. Pharmacological analysis showed that the administration of two cell‐cycle inhibitors for inactivating CDC25A phosphatase (NSC95397) and the cyclin E2/cyclin‐dependent kinase 2 complex (purvalanol A) increased the dome number independently of MTA. Altogether, our results indicate that MTA is the minimum unit required to induce dome formation, with the down‐regulation of CDC25A and possibly CCNE2 being important steps in this process.

Abstract
Piperitenone oxide, a major chemical constituent of the essential oil of spearmint, Mentha spicata, induces differentiation in human colon cancer RCM-1 cells. In this study, piperitenone oxide and trans-piperitenone dioxide were prepared as racemic forms by epoxidation of piperitenone. The relative configuration between two epoxides in piperitenone dioxide was determined to be trans by 1H NMR analysis and nuclear Overhauser effect spectroscopy (NOESY) in conjunction with density functional theory (DFT) calculations. Optical resolution of (±)-piperitenone oxide by high-performance liquid chromatography (HPLC) using a chiral stationary phase (CSP) afforded both enantiomers with over 98% enantiomeric excess (ee). Evaluation of the differentiation-inducing activity of the synthetic compounds revealed that the epoxide at C-1 and C-6 in piperitenone oxide is important for the activity, and (+)-piperitenone oxide has stronger activity than (-)-piperitenone oxide. The results obtained in this study provide new information on the application of piperitenone oxide and spearmint for differentiation-inducing therapy. Furthermore, natural piperitenone oxide was isolated from M. spicata. The enantiomeric excess of the isolated natural piperitenone oxide was 66% ee. Epoxidation of piperitenone with hydrogen peroxide proceeded in a phosphate buffer under weak basic conditions to give (±)-piperitenone oxide. These results suggest that the nonenzymatic epoxidation of piperitenone, which causes a decrease in the enantiomeric excess of natural piperitenone oxide, is accompanied by an enzymatic epoxidation in the biosynthesis of piperitenone oxide.

Abstract
The fruit of Katsura-uri (Japan's heirloom pickling melon, Cucumis melo var. conomon) possesses a fruity aroma and moderate sweetness. The fruit juice has potential to minimize human postprandial blood glucose levels. This study provides information regarding the health benefits of Katsura-uri and its utility in treating diabetes. The study methodology involved measuring the color and firmness of Katsura-uri fruit at five ripening stages, and quantitation of the aroma substances, proximate composition, and sugars. Significant changes were detected in the color, firmness, and level of aroma substances with ripening of Katsura-uri fruit, albeit with no major changes in proximate composition, with the exception of dietary fiber, and sugars. To determine the effects of Katsura-uri juice, the blood glucose levels of ten diabetic volunteers aged 46-75 y were monitored after its consumption, and compared with after consumption of muskmelon juice equivalent to the total weight of Katsura-uri juice. The blood glucose area under the curve level was significantly lower after consumption of Katsura-uri juice (16±5 h • mg/dL) than after consumption of muskmelon juice (55±17 h • mg/dL; p<0.05). The level of the glucose spike was also significantly lower after consumption of Katsura-uri juice (22±5 mg/dL) than after consumption of muskmelon juice (64±6 mg/dL; p<0.05). The completely ripe Katsura-uri fruit provides the best results for diabetic subjects, which is the first case of fruits sweetened with the addition of zero-calorie sweeteners.

Abstract
Arabidopsis bHLH-type transcription factors-BRASSINOSTEROID INSENSITIVE 1-EMS-SUPPRESSOR 1 (BES1) and BRASSINAZOLE RESISTANT 1 (BZR1)-play key roles in brassinosteroid (BR) signaling. By contrast, the functions of the other four BES1/BZR1 homologs (BEH1-4) remain unknown. Here, we describe the detailed expression profiles of the BES1/BZR1 family genes. Their expressions were distinct regarding growth-stage dependence and organ specificity but exhibited some overlaps as well. Furthermore, their mRNA levels mostly remained unchanged responding to seven non-BR phytohormones. However, BEH1 and BEH2 were downregulated by brassinolide, suggesting a close association with the BR function. Additionally, BEH4 was ubiquitously expressed throughout the life of the plant but displayed some expression preference. For instance, BEH4 expression was limited to guard cells and the adjacent pavement cells in the leaf epidermis and was induced during growth progression in very young seedlings, suggesting that BEH4 is specifically regulated in certain contexts, although it is almost constitutively controlled.

Abstract
Mutualism based on reciprocal exchange of costly services must avoid exploitation by 'free-rides'. Accordingly, hosts discriminate against free-riding symbionts in many mutualistic relationships. However, as the selective advantage of discriminators comes from the presence of variability in symbiont quality that they eliminate, discrimination and thus mutualism have been considered to be maintained with exogenous supply of free-riders. In this study, we tried to resolve the 'paradoxical' co-evolution of discrimination by hosts and cooperation by symbionts, by comparing two different types of discrimination: 'one-shot' discrimination, where a host does not reacquire new symbionts after evicting free-riders, and 'resampling' discrimination, where a host does from the environment. Our study shows that this apparently minor difference in discrimination types leads to qualitatively different evolutionary outcomes. First, although it has been usually considered that the benefit of discriminators is derived from the variability of symbiont quality, the benefit of a certain type of discriminators (e.g. one-shot discrimination) is proportional to the frequency of free-riders, which is in stark contrast to the case of resampling discrimination. As a result, one-shot discriminators can invade the free-rider/nondiscriminator population, even if standing variation for symbiont quality is absent. Second, our one-shot discriminators can also be maintained without exogenous supply of free-riders and hence is free from the paradox of discrimination. Therefore, our result indicates that the paradox is not a common feature of evolution of discrimination but is a problem of specific types of discrimination.

Abstract
The aim of the present study is to evaluate the outcome of hand-sewn esophagogastric anastomosis during radical esophagectomy for esophageal cancer. The outcomes of 467 consecutive esophageal cancer patients who underwent cervical esophagogastric anastomosis using interrupted and double-layered sutures after radical esophagectomy via right thoracotomy or thoracoscopic surgery were retrospectively reviewed. Anastomotic leakage, including conduit necrosis, occurred in 11 of 467 patients (2.4%); 7 of 11 (63.6%) cases experienced only minor leakage, whereas the other four (36.4%) patients had major leakage that required surgical or radiologic intervention, including two patients of conduit necrosis. Anastomotic leakages were more frequently observed after retrosternal reconstruction compared with the posterior mediastinal route (P < 0.0001). The median time to healing of leakage was 40 days (range: 14-97 days). Two patients (2/467, 0.4%) died in the hospital due to sepsis caused by the leakage and conduit necrosis. Twelve patients (2.6%) developed anastomotic stenosis, which was improved by dilatation in all patients. Hand-sewn cervical esophagogastric anastomosis is a stable and highly safe method of radical esophagectomy for esophageal cancer.

Abstract
Shear stress can result in fatigue, damage, and irreversible deformation of the temporomandibular joint disc. Insight into the dynamic shear properties of the disc may give insight into the mechanism inducing tissue failure due to shear. We tested the hypothesis that the dynamic shear properties of the disc depend on the amount of shear and compressive strain. Twenty-four porcine discs were used for dynamic shear tests. The specimens were clamped between the plates of a loading apparatus under compressive strains of 5%, 10%, and 15%. Dynamic shear was applied to the specimen by a sinusoidal strain of, respectively, 0.5%, 1.0%, and 1.5%. Both the dynamic elasticity and viscosity were proportional to compressive strain and inversely proportional to shear strain. These shear characteristics suggest a significant role of compressive and shear strain on the internal friction of the disc.

Abstract
To examine the effects of 4-methylthio-3-butenyl isothiocyanate on esophageal carcinogenesis, male 6-week-old F344 rats were subcutaneously injected with 0.5 mg/kg body weight N-nitrosomethylbenzylamine three times per week for 5 weeks and fed a diet supplemented with 80 ppm 4-methylthio-3-butenyl isothiocyanate, equivalent to 6.05 mg/kg body weight/day for the initiation stage, 4.03 mg/kg body weight/day for the promotion stage, or 4.79 mg/kg body weight/day for all stages. Although the incidence of lesions was not affected by 4-methylthio-3-butenyl isothiocyanate treatment, the multiplicity of squamous cell papilloma in the esophagus was significantly decreased in rats in the 4-methylthio-3-butenyl isothiocyanate initiation stage group (1.13 ± 0.74), 4-methylthio-3-butenyl isothiocyanate promotion stage group (1.47 ± 0.99), and 4-methylthio-3-butenyl isothiocyanate all stage group (1.47 ± 1.13) as compared with rats treated with N-nitrosomethylbenzylamine alone (3.00 ± 1.46). Immunohistochemical analysis revealed that 4-methylthio-3-butenyl isothiocyanate induced apoptosis, suppressed cell proliferation, and increased p21 expression when administered in the promotion phase. These modifying effects were not observed in the rats treated with 4-methylthio-3-butenyl isothiocyanate alone. Our results indicated that 4-methylthio-3-butenyl isothiocyanate may exert chemopreventive effects against N-nitrosomethylbenzylamine-induced esophageal carcinogenesis in rats.

Abstract
BACKGROUND Little is known about correlates of vitamin D status in Asian populations. In this study, we established the prevalence of vitamin D sufficiency in the Murakami region (latitude N38°13') in Niigata, Japan, and examined demographic, environmental, and lifestyle factors that might be associated with vitamin D sufficiency, with the aim of clarifying the relative contributions of previously described determinants of vitamin D status as well as identifying new determinants in this Japanese population. METHODS This study involved a cross-sectional analysis of baseline data obtained from a cohort study conducted in 2011-2013. Participants were 9084 individuals aged between 40 and 74 years who provided blood samples for the determination of plasma 25-hydroxyvitamin D [25(OH)D] concentrations. Lifestyle information was obtained from 8498 participants, with some missing values regarding different lifestyle factors. Multiple logistic regression analysis was used to obtain odds ratios for vitamin D sufficiency, which was defined as a plasma 25(OH)D concentration ≥ 75 nmol/L. RESULTS The prevalence of vitamin D sufficiency (i.e., plasma 25(OH)D concentration ≥ 75 nmol/L) was 9.1%, and significant associations were observed with male gender (P<0.0001; OR=2.37, 95% CI: 1.84-3.05), older age (P for trend <0.0001), lower BMI (P for trend <0.0001), higher METs score (P for trend=0.0138), higher vitamin D intake (P for trend=0.0467), summer season (P for trend <0.0001), longer duration outdoors (P for trend=0.0026), no sunscreen use (P=0.0135; OR=1.40, 95% CI: 1.07-1.82), higher salmon consumption (P for trend <0.0001), higher alcohol consumption (P for trend <0.0001), and lower coffee consumption (P for trend=0.0025). Unlike other populations previously reported, vitamin D sufficiency was associated with older age. CONCLUSIONS The prevalence of vitamin D sufficiency (i.e., 25[OH]D ≥ 75 nmol/L) was low (9.1%) in this Japanese population. A number of demographic, environmental, and lifestyle factors are associated with vitamin D sufficiency, and thus lifestyle modification may present an opportunity to achieve vitamin D sufficiency.

Abstract
To achieve enhanced nitrogen removal, we modified a cultivation system with circulated irrigation of treated municipal wastewater by using rice for animal feed instead of human consumption. The performance of this modified system was evaluated through a bench-scale experiment by comparing the direction of circulated irrigation (i.e. passing through paddy soil upward and downward). The modified system achieved more than three times higher nitrogen removal (3.2 g) than the system in which rice for human consumption was cultivated. The removal efficiency was higher than 99.5%, regardless of the direction of circulated irrigation. Nitrogen in the treated municipal wastewater was adsorbed by the rice plant in this cultivation system as effectively as chemical fertilizer used in normal paddy fields. Circulated irrigation increased the nitrogen released to the atmosphere, probably due to enhanced denitrification. Neither the circulation of irrigation water nor its direction affected the growth of the rice plant and the yield and quality of harvested rice. The yield of rice harvested in this system did not reach the target value in normal paddy fields. To increase this yield, a larger amount of treated wastewater should be applied to the system, considering the significant amount of nitrogen released to the atmosphere.

Abstract
PURPOSE Weight retention during the postpartum period is critical for the later development of obesity in women. Traditional physical activity is frequently discontinued because of incompatibility with mothers' agenda (i.e., baby care). In the present study, active video games (AVG) are proposed for postpartum women to improve their body composition. METHODS Thirty-four postpartum women (body mass index = 24.5 ± 3.4 kg·m) were randomized to an AVG group or a control group. Subjects assigned to the AVG group were given a Wii Nintendo console with the game Wii Fit Plus for 40 d. The two groups were tested for weight, body mass index, body fat mass, waist and hip circumferences, and other anthropometric parameters. Physical fitness, energy expenditure, energy intake, and adverse events were also investigated. RESULTS The AVG group lost more weight than the control group (-2.2 ± 0.9 vs. -0.5 ± 0.7 kg, P < 0.001). They also exhibited more important reductions of BMI, waist and hip circumferences, and body fat (P < 0.05). During the 40-d period, subjects expended an estimated 4682 ± 2874 kcal just by playing AVG. Daily energy intake was reduced by 206 ± 559 kcal. There were significant positive correlations between playing frequency, total playing time, total energy expenditure during the 40-d period, and decrease in daily energy intake respectively, and weight loss (P < 0.05). Playing time data suggested no conflict with baby care activities. CONCLUSIONS AVGs could represent an interesting spare physical activity for postpartum women. In the present study, these games promoted physical activity, induced a reduction of energy intake, and subsequently minimized weight retention.

The spin-orbit interaction plays a crucial role in diverse fields of condensed matter, including the investigation of Majorana fermions, topological insulators, quantum information and spintronics. In III-V zinc-blende semiconductor heterostructures, two types of spin-orbit interaction--Rashba and Dresselhaus--act on the electron spin as effective magnetic fields with different directions. They are characterized by coefficients α and β, respectively. When α is equal to β, the so-called persistent spin helix symmetry is realized. In this condition, invariance with respect to spin rotations is achieved even in the presence of the spin-orbit interaction, implying strongly enhanced spin lifetimes for spatially periodic spin modes. Existing methods to evaluate α/β require fitting analyses that often include ambiguity in the parameters used. Here, we experimentally demonstrate a simple and fitting parameter-free technique to determine α/β and to deduce the absolute values of α and β. The method is based on the detection of the effective magnetic field direction and the strength induced by the two spin-orbit interactions. Moreover, we observe the persistent spin helix symmetry by gate tuning.

Abstract
PURPOSE Total extraperitoneal preperitoneal (TEP) repair is widely used for inguinal, femoral, or obturator hernia treatment. However, mesh repair is not often used for strangulated hernia treatment if intestinal resection is required because of the risk of postoperative mesh infection. Complete mesh repair is required for hernia treatment to prevent postoperative recurrence, particularly in patients with femoral or obturator hernia. CASES We treated four patients with inguinocrural and obturator hernias (a 72-year-old male with a right indirect inguinal hernia; an 83-year-old female with a right obturator hernia; and 86- and 82-year-old females with femoral hernias) via a two-stage laparoscopic surgery. All patients were diagnosed with intestinal obstruction due to strangulated hernia. First, the incarcerated small intestine was released and then laparoscopically resected. Further, 8-24 days after the first surgery, bilateral TEP repairs were performed in all patients; the postoperative course was uneventful in all patients, and they were discharged 5-10 days after TEP repair. At present, no hernia recurrence has been reported in any patient. CONCLUSION The two-stage laparoscopic treatment is safe for treatment of strangulated inguinal, femoral, and obturator hernias, and complete mesh repair via the TEP method can be performed in elderly patients to minimize the occurrence of mesh infection.

Abstract
Maternal obesity and overconsumption of saturated fats during pregnancy have profound effects on offspring health, ranging from metabolic to behavioral disorders in later life. The influence of high-fat diet (HFD) exposure on the development of brain regions implicated in anxiety behavior is not well understood. We previously found that maternal HFD exposure is associated with an increase in anxiety behavior and alterations in the expression of several genes involved in inflammation via the glucocorticoid signaling pathway in adult rat offspring. During adolescence, the maturation of feedback systems mediating corticosteroid sensitivity is incomplete, and therefore distinct from adulthood. In this study, we examined the influence of maternal HFD on several measures of anxiety behavior and gene expression in adolescent offspring. We examined the expression of corticosteroid receptors and related inflammatory processes, as corticosteroid receptors are known to regulate circulating corticosterone levels during basal and stress conditions in addition to influencing inflammatory processes in the hippocampus and amygdala. We found that adolescent animals perinatally exposed to HFD generally showed decreased anxiety behavior accompanied by a selective alteration in the expression of the glucocorticoid receptor and several downstream inflammatory genes in the hippocampus and amygdala. These data suggest that adolescence constitutes an additional period when the effects of developmental programming may modify mental health trajectories.

Abstract
Trans-cervical insemination (TCI) with cryopreserved semen offers a potentially effective approach for breeding canids with specific genetic traits, such as guide dogs for the blind. However, there are technical difficulties in canine sperm cryopreservation, such as the composition of semen extender. The aim of this study was to evaluate the effects of glutathione (GSH) as an antioxidant in the semen extender to improve the quality of frozen-thawed dog sperm. A Tris-egg yolk-citrate extender containing 15.7 mg mL–1 of TRIS, 8.8 mg mL–1 of citric acid, 14.1 mg mL–1 of lactose, 25.4 mg mL–1 of raffinose, 1% (vol/vol) antibiotics, and 20% (vol/vol) egg yolk in ultra-pure water was used as the base medium. Twelve ejaculates were collected from 7 dogs. Each ejaculate was divided into 2 to 5 aliquots and extended with base extender supplemented with 0, 2.5, 5, 7.5, and 10 mM GSH as first dilution. The extended semen was equilibrated for 3 h at 4°C. An equal volume of second extender was added to obtain a final concentration of 6.5% glycerol and sperm per milliliter. The sperm samples were loaded in straws and frozen at 6 cm above the surface of LN2 for 15 min in a styrene foam box and plunged into the LN2. The frozen semen was thawed for evaluation. The motility of sperm was estimated with a phase-contrast microscope and the motile patterns were classified into the following grades: progressively motile at a high speed (+++), progressively motile at a moderate and low speed (++), motile without progression (+), and immotile (–). Then, the sperm motility index (SMI) was determined from the following formula as described previously (Iritani et al., 1975), with some modifications: the percentage of (+++) sperm + the percentage of (++) sperm × 0.75 + the percentage of (+) sperm × 0.5. Sperm motility and the SMI were determined at 0, 1, 2, 3, 4, 12, and 24 h after thawing. Acrosome status was evaluated at 4 h after thawing. Lipid peroxidation (LP) levels at 0 and 12 h after thawing were used to examine the antioxidant ability of GSH. Trans-cervical insemination was carried out on 5 bitches to evaluate the fertility of GSH-treated sperm. The TCI were performed nonsurgically with a laparoscope and deposited 2 mL of semen through a catheter. Each bitch was inseminated 1 to 2 times during oestrus. Data were analysed using ANOVA with the Tukey-Kramer method. We found that the rate of (+++) sperm in the 5 mM GSH group was higher than that in the 0 mM group from 1 to 24 h after thawing (P < 0.05). The SMI was higher in the 5 and 7.5 mM GSH groups than in the 0 mM group (P < 0.05). There were no significant differences in the control and 2.5 and 10 mM GSH groups. Long-term survival was increased in the 5 mM GSH group. Acrosome integrity was higher in the GSH-treated group. The level of LP was lower in the GSH-treated groups at 0 h after thawing (P < 0.05). Trans-cervical insemination with the 5 mM GSH-treated semen resulted in the delivery of 5 pups from 2 bitches. These results indicate that the cryopreservation with 5 mM GSH can improve the motility, viability, and fertility of frozen-thawed canine sperm by its antioxidant effects on the sperm membrane.

Abstract
Masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) is a new disease associated with limited mouth opening that is often misdiagnosed as a temporomandibular disorder; subsequently, patients are mistakenly treated with irreversible operations. Due to the poor presentation and characterization of symptoms, the underlying pathological conditions remain unclear. We have previously conducted a proteomic analysis of tendons derived from one MMTAH subject and one facial deformity subject using two-dimensional fluorescence difference gel electrophoresis and liquid chromatography coupled with tandem mass spectrometry. However, the results were obtained for only one subject. The aim of the present study was to confirm the expression of specific molecules in tendon tissues from multiple subjects with MMTAH by applying two-dimensional polyacrylamide gel electrophoresis with matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Of the 19 proteins identified in tendons from both MMTAH and facial deformity patients, fibrinogen fragment D and beta-crystallin A4 were up-regulated, whereas myosin light chain 4 was down-regulated in MMTAH. We also found fibrinogen to be expressed robustly in tendon tissues of MMTAH patients. Our data provide the possibility that the distinctive expression of these novel proteins is associated with the pathology of MMTAH.
