In satsuma mandarin fruit (Citrus unshiu Marc.), β-cryptoxanthin is a major carotenoid and an important quality component in the juice sacs. The stage of maturity and storage conditions of satsuma mandarin fruit shipped to markets varies. However, the effects of maturation stage, storage temperature and duration on changes in β-cryptoxanthin content have not been fully studied. In the present study, fruits were harvested at different maturation stages, and changes in β-cryptoxanthin content in the juice sacs were investigated during storage at temperatures from 5 to 20°C. At 20°C, in fruit harvested while β-cryptoxanthin is still being accumulated on the tree, the content continued to increase following 15 days of storage. However, in the fruit without β-cryptoxanthin accumulation on the tree, the content did not increase. At 10°C, in the fruit accumulating β-cryptoxanthin on the tree, the content continued to increase after 14 days’ storage, whereas in the fruit without β-cryptoxanthin accumulation, the content did not increase after 14 days’ storage but increased after 30 days’ storage. At 8°C, the increase in content was also observed in the fruit when stored for 80 days. In contrast, at 5°C, the content did not change notably at any maturation stage regardless of the experimental period. The changes in the carotenoid content and gene expression suggest that carotenoid accumulation during on-tree maturation continues after harvest at 20°C, but not at 5°C. The present results suggest that β-cryptoxanthin content will not decrease at a range from 5 to 20°C irrespective of the maturation stage. Moreover, at 8°C and above, the β-cryptoxanthin content will gradually increase, and the rate will be more rapid in fruit harvested when carotenoid accumulation is in progress on the tree.

Background: It is unclear whether either neighborhood collective efficacy or school collective efficacy is associated with adolescent alcohol use. This study aimed to examine the relative contributions of collective efficacy, both in school and in the neighborhood contexts, to alcohol use among Japanese adolescents.Methods: A cross-sectional study was conducted in public high schools across Okinawa and Ibaraki Prefectures in Japan in 2016. The study participants consisted of 3,291 students in grades 10 through 12 cross-nested in 51 schools and 107 neighborhoods. Alcohol use was measured as current alcohol drinking, which was defined as self-reported drinking on at least 1 day in the past 30 days. Collective efficacy was measured using scales of social cohesion and informal social control in school and the neighborhood. Contextual-level collective efficacy was measured using aggregated school-level and neighborhood-level individual responses, respectively. We used non-hierarchical multilevel models to fit the cross-nested data.Results: Significant variation in alcohol use was shown between schools but not between neighborhoods. After adjusting for covariates, school collective efficacy at individual- and contextual-levels was protectively associated with alcohol drinking (odds ratio [OR] for the increase of one standard deviation from the mean 0.72; 95% confidence interval [CI], 0.63–0.82 and OR 0.61; 95% CI, 0.49–0.75, respectively), whereas neighborhood collective efficacy at individual- and contextual-levels was not associated with alcohol consumption.Conclusion: The school-level associations of collective efficacy with adolescent alcohol use may have the greater impact than the neighborhood-level associations. Adolescent drinking prevention efforts should include enhancing school collective efficacy.

Giant clams are simultaneous hermaphrodites and are assumed to ejaculate first and, after completely stopping ejaculation, release eggs. In the seed production method aimed at preventing self-fertilization, each adult clam is induced to ejaculate in a tank and then release eggs in another tank. Giant clams, however, have recently been suggested to continue ejaculation for a period after the beginning of egg release. The overlap between ejaculation and egg release might lead to self-fertilization in the tank used for egg release, especially for the eggs released just at the beginning of spawning. We examined the possibility of such self-fertilization for the giant clam Tridacna crocea and obtained three results. (1) In observations with the naked eye in a laboratory, 2 of 38 T. crocea simultaneously ejaculated and released eggs. (2) In a laboratory experiment, 1.5 to 80.0% of eggs released from each adult clam developed into D-shaped larvae without artificial cross-fertilization. Such development occurred more frequently for the eggs released earlier from each adult clam than for the eggs released later from the clam. (3) In observations at a hatchery, 2 to 94% of the eggs released from 4 of 5 adults were found to develop into D-shaped larvae without artificial cross-fertilization. The three results suggest that at least some T. crocea adults continue ejaculation for a period after starting spawning eggs, which causes self-fertilization.

A 6-year 5-month-old spayed female Scottish Fold cat presented with a one-month history of gait abnormalities, increased salivation, and decreased activity. A blood test showed hyperammonemia and increased serum bile acids. Imaging tests revealed multiple shunt vessels indicating acquired portosystemic shunt. Histopathologic analysis of liver biopsy showed features consistent with liver hypoperfusion, such as a barely recognizable portal vein, increased numbers of small arterioles, and diffuse vacuolar degeneration of hepatocytes. These findings supported the diagnosis of primary hypoplasia of the portal vein/microvascular dysplasia, (PHPV/MVD). To our knowledge, this is the first case of feline PHPV/MVD that developed multiple acquired portosystemic shunts and presented with hepatic encephalopathy.

A high-throughput method was developed to analyze five barbiturates (phenobarbital, cyclobarbital, amobarbital, secobarbital, and thiopental) and a metabolite in human body samples using a new Monolithic C18 gel-packed Spin Tip and ultra-performance liquid chromatography (UPLC)-quadrupole-time-of-flight (Q-ToF) mass spectrometry (MS). Plasma (20µl) or urine (100µl) samples spiked with the five barbiturates and 5-(4-methylphenyl)-5-phenylhydantoin (internal standard, IS) were mixed with distilled water. The mixture was extracted using the Monolithic C18 Spin Tip, and the analytes retained on the C18 phase were then eluted with methanol. The eluate was injected directly into an analytical column (Waters Acquity BEH C18, 50mm×2.1mm i.d., particle size 1.7µm), and quantified by Q-ToF-MS with negative-ion electrospray ionization (ESI). Good separation and clear peak shapes of the five drugs were achieved within an analysis time of 6min, including the extraction time. All drugs spiked in the plasma showed recoveries of 86-98%. The regression equations for the five drugs showed excellent linearities in the range of 5-500ng/20µl of plasma, with limits of detection and i-Fit of 1ng/20µl. The method was also successfully applied to determine the level of amobarbital and its metabolite in human plasma and urine, respectively, after oral administration to a volunteer. This new method could be applied widely in the clinical and forensic fields for the quantitative determination of drugs and metabolites.

The new geostationary meteorological satellite of the Japan Meteorological Agency (JMA), Himawari-8, entered operation on 7 July 2015. Himawari-8 features the new 16-band Advanced Himawari Imager (AHI), whose spatial resolution and observation frequency are improved over those of its predecessor MTSAT-series satellites. These improvements will bring unprecedented levels of performance in nowcasting services and short-range weather forecasting systems. In view of the essential nature of navigation and radiometric calibration in fully leveraging the imager’s potential, this study reports on the current status of calibration for the AHI. Image navigation is accurate to within 1 km, and band-to-band co-registration has also been validated. Infrared-band calibration is accurate to within 0.2 K with no significant diurnal variation, and is being validated using an approach developed under the GSICS framework. Validation approaches are currently being tested for the visible and near-infrared bands. Two such approaches were compared and found to produce largely consistent results.

近年、芸術文化の持つ創造性を都市再生につなげようとする創造都市論への関心が高まり、そのコアというべき概念である「創造の場」への注目が集まっている。本稿の主題は、別府市におけるアートNPO BEPPU PROJECTを中心とする実践事例を詳述したうえで、拙稿(2009)による「創造の場」4類型にもとづいて実証的考察を加えることにある。これによって得られる結論は、この事例の創造的営為が「創造の場」に依拠しており、またその形成を意図した活動であること、4類型が「創造の場」の基本的な分析フレームとして有効であるとの証左が得られることである。さらに、創造的営為には空間の大きさや開放性など多様なあり方を示す「創造の場」とその連鎖が必要であり、「創造の場」の形成のためにはアートNPO と行政等のネットワーク構築が重要であることが示唆される。

Background:We determined the 2-year long-term risk-benefit profile in patients with stroke or transient ischemic attack (TIA) receiving warfarin or direct oral anticoagulants (DOACs) for nonvalvular atrial fibrillation (NVAF) using a prospective, multicenter, observational registry in Japan.Methods and Results:NVAF patients within 7 days after onset of ischemic stroke/TIA were enrolled in 18 stroke centers. Outcome measures included ischemic and bleeding events and death in the 2-year follow-up period. We enrolled 1,116 patients taking either warfarin (650 patients) or DOACs (466 patients) at acute hospital discharge. DOAC users were younger and had lower National Institutes of Health Stroke Scale, CHADS2and discharge modified Rankin Scale scores than warfarin users (P<0.0001 each). Incidences of stroke/systemic embolism (adjusted hazard ratio, 1.07; 95% CI, 0.66–1.72), all ischemic events (1.13; 0.72–1.75), and ischemic stroke/TIA (1.58; 0.95–2.62) were similar between groups. Risks of intracranial hemorrhage (0.32; 0.09–0.97) and death (0.41; 0.26–0.63) were significantly lower for DOAC users. Infection was the leading cause of death, accounting for 40% of deaths among warfarin users.Conclusions:Stroke/TIA patients receiving DOACs for secondary prevention were younger and had lower stroke severity and risk indices than those receiving warfarin. Estimated cumulative incidences of stroke and systemic embolism within 2 years were similar between warfarin and DOACs users, but those of death and intracranial hemorrhage were significantly lower among DOAC users.

A 12-year-old intact male Welsh Corgi was presented with enlargement of the right scrotum. Both testicles were surgically removed and histopathologically examined. On gross examination, white nodules were found in the epididymis and ductus deferens. Histopathologically, the nodules developed continuously from the tunica vaginalis testis of the right scrotum and consisted of spindle-shaped neoplastic cells that invaded the surrounding tissue. Immunohistochemically, the neoplastic cells were diffusely positive for vimentin, cytokeratin and Wilms tumor-1 (WT-1). Based on these findings, the tumor was diagnosed as sarcomatoid mesothelioma. The dog presented with respiratory distress 122 days after surgery and clinical examination found multiple metastatic lesions in the lung, abdominal lymph nodes and peritoneum. The dog died 144 days after surgery due to disease progression.

In Japan, overwork-related disorders occur among local public employees as well as those in private businesses. However, to date, there are no studies reporting the state of compensation for cerebrovascular/cardiovascular diseases (CCVD) and mental disorders due to overwork or work-related stress among local public employees in Japan over multiple years. This report examined the recent trend of overwork-related CCVD and mental disorders, including the incidence rates of these disorders, among local public employees in Japan from the perspective of compensation for public accidents, using data from the Japanese Government and relevant organizations. Since 2000, compared to CCVD, there has been an overall increase in the number of claims and cases of compensation for mental disorders. Over half of the individuals receiving compensation for mental disorders were either in their 30s or younger. About 47% of cases of mental disorders were compensated due to work-related factors other than long working hours. The incidence rate by job type was highest among "police officials" and "fire department officials" for compensated CCVD and mental disorders cases, respectively. Changes in the trend of overwork-related disorders among local public employees in Japan under a legal foundation should be closely monitored.

A tyrosine protein kinase inhibitor, erbstatin, showed no antineoplastic effect on L-1210 mouse leukemia when it was injected alone. Erbstatin was found to be inactivated by incubation in serum, but not in dialyzed serum. It was also inactivated in reconstituted serum containing dialyzed serum components and ferric or ferrous ion. Because erbstatin was considered to be inactivated by the ferric or ferrous ion in serum, foroxymithine, which is a potent chelator for the ferric ion, was given to the mice together with erbstatin. Administration of both erbstatin and foroxymithine showed antineoplastic activity against L-1210 leukemia.

A 52-year-old man who had been taking omeprazole, a proton pump inhibitor (PPI), for 25 years developed iron deficiency anemia. An evaluation of the entire gastrointestinal tract did not reveal any possible causes of gastrointestinal blood loss. The cause of the iron deficiency was considered to be a reduction in gastrointestinal iron absorption in association with the reduced secretion of gastric acid due to PPI use. This case demonstrates that long-term PPI use for as long as 25 years may cause iron deficiency anemia and should be considered in the differential diagnosis of iron deficiency anemia in long-term PPI users.
