当院健診センターは平成10年度より, 胃バリウム検査に加えて希望者を対象とした血清ペプシノゲン値の測定を開始した。過去5年間の併用法発見胃癌数は94例であり, 平均胃癌検出率はバリウム法で79.8%, ペプシノゲン法で71.3%となり, バリウム法が高かった。一方, 両検査法が陽性を示したものは51.1%, バリウム法のみ陽性癌は28.7%, バリウム法陰性でPG法のみ陽性癌は20.2%であり約半数の48.9%がどちらか一方で拾い上げられていたことから, 両法は相補的な関係にあると思われ, 併用法の有用性が再確認できた。PGレベル区分の検討では陽性反応的中率でレベル2以上, 経年変化で特に陰性からレベル2, 4への移行群で高く, より高危険群の設定が可能と思われた。

記銘項目が実験者によって割り当てられる場合よりも,実験参加者自身により選択される場合のほうが記憶保持は優れる.この自己選択効果の生起には,選択肢項目間の相対比較が必要である可能性が示唆されているが(伊藤・綾部・菊地,2012),相対比較の際に意味水準での特徴にアクセスすることが記憶を促した可能性は否定できない(処理水準効果).本研究の偶発学習段階において実験参加者は,意味水準か非意味水準の特徴に基づいて二つの選択肢項目間の相対比較を行うか,単独の項目に対して意味水準か非意味水準で判断を行った.その結果,二つの項目間で相対比較が行われた場合にも,単独の項目に対して判断が行われた場合にも,再生成績における処理水準効果が認められた.さらに重要なことに,処理水準にはかかわらず項目間の相対比較による記憶の促進が認められた.よって,記憶における自己選択効果の生起には選択の際の相対比較が必要であり,処理水準効果のみが貢献しているとは言えない可能性が示唆された.

要旨:高次脳機能障害に特有のリハビリテーション(以下,リハ)医療や専門的社会支援を必要とする患者のほぼ半数を脳血管障害が占めるとの報告があり(蜂須賀ら2011),脳卒中診療においても高次脳機能障害のリハと職場復帰は大きな課題である.リハにおいて記憶障害への対策は重要で,軽度の記憶障害においては視覚イメージの利用や手帳の活用などの記憶トレーニングが,重度の記憶障害においては外的代償手段の使用や誤りなし学習法が奨められている(Ciceroneら2011).高次脳機能障害は能動的に行動しない入院生活では問題となりにくい.本人にも周囲にも「目に見えない障害」を抱えて職場復帰した結果,能力や勤労意欲を欠くとみなされやすく注意を要する.また,その障害特性より就労後に新たな問題を生じてきやすい.個々の症例に応じて産業医や利用可能な社会資源とも連携し,就労継続支援を丁寧に行うことが重要である.

The Tachikawa fault, which is the only active fault in the Tokyo Metropolis, is expected to be the source of shallow intra-plate earthquakes in the future. We performed additional trenching surveys at the northwestern part of the fault to obtain the paleoseismological parameters for evaluating earthquake potential caused by the fault. Trench wall observation, radiocarbon dating, and tephra analyses constrained the last surface-rupturing event at the Tachikawa fault between about 13, 700 cal yBP and 12, 800 cal yBP. The vertical separation of the event is estimated to be more than 2.6 meters.

Background: In this cohort study, we investigated whether a diagnosis of herpes zoster (HZ) was associated with a higher risk of subsequent cancer as compared with the Taiwanese general population.Methods: Data were obtained from the Taiwan National Health Insurance Research Database. In total, 38 743 patients who were aged 50 years or older and had received ambulatory care for HZ between 1997 and 2006 were identified as the study cohort; 116 229 age- and sex-matched patients without HZ were included as the comparison cohort. We used Cox proportional hazards regression models to estimate the hazard ratios (HRs) for subsequent cancer, after controlling for potential confounders.Results: The HR for subsequent cancer varied according to time since HZ diagnosis. The HR was 1.58 (95% CI, 1.38–1.80) within the first year, 1.30 (95% CI, 1.15–1.46) between 1 and 2 years, 1.10 (95% CI, 0.98–1.24) between 2 and 3 years, 1.02 (95% CI, 0.91–1.15) between 3 and 4 years, and 1.08 (95% CI, 0.96–1.21) between 4 and 5 years. The risk of subsequent cancer, particularly lung cancer, was significantly higher during the first 2 years after initial diagnosis of HZ.Conclusions: Our findings suggest that an HZ diagnosis is a marker of occult malignancy, particularly in lung cancer. The HRs for cancer decreased gradually over time and were no longer significant after 2 years of follow-up, which indicates that the association between HZ and cancer is likely due to detection bias.

Succeeding to the previous papers, the present paper deals with the presence of Cd113m. Group II, separated directly from the raw ashes of the liver or the pyloric caeca of skipjacks, Katsuwonus pelamis, or from the radio active fration, “6-L-F2”, obtained by ion-exchange resin, was fractionated further into each member (Fig. 1). The considerable activity was found in Cd-fraction in both cases (Table 1). The Cd-fraction showed no decay in 50 days and no γ-ray emission. The maximum energy was found to be 0. 6 MeV., when calculated from the absorption curve (Fig. 2). From these results, the nuclide in question was identified as Cd113m. The weak activity was also found in Sn-fraction in the above fractionation, but the nuclide has not yet been identified.

Analysis of lightning electromagnetic field using the FDTD method have been studied in recent year. However, large-scale three-dimensional analysis on real environment have not been considered, because the FDTD method has huge computational cost on large-scale analysis. So we have proposed a three-dimensional moving window FDTD (MW-FDTD) method with parallel computation. Our method use few computational cost than the conventional FDTD method and the original MW-FDTD method. In this paper, we have studied about computation performance of MW-FDTD parallel computation and large-scale three-dimensional analysis of lightning electromagnetic field on a real terrain model using our MW-FDTD with parallel computation.

On coral reefs, sites that receive consistently high levels of recruitment relevant to other sites (“recruitment hotspots”) may be crucial to the persistence of populations. However, few studies of coral recruitment have the necessary replication in space and time required to detect recruitment hotspots. The aim of this study was to detect recruitment hotspots at One Tree Reef (southern Great Barrier Reef) and to explore associations between hotspots, hydrodynamics, adult abundance and reef benthos. Recruitment hotspots were detected on the reef slope and in the lagoon. Almost all hotspots were located on the leeward side of the reef, however, there was little congruence among hotspots for different families of coral recruits. Recruitment hotspots in some taxa in some habitats were correlated with water flow or adult abun-dance. A clear recruitment hotspot for two families (Pocilloporidae and Poritidae) in the lagoon had medium levels of water flow (∼4 cm s-1), but there was no re-lationship with water flow on the slope. In experimental aquaria, Acropora nasuta settlement was six to 10 times greater under low (2.1 cm s-1) compared to medium water flow (4.6 cm s-1). Abundance of pocilloporid and poritid, but not acroporid, recruits at each site was often correlated with adult cover indicating either aggregative settlement or limited dispersal. Recruitment hotspots are likely to be both sources and sinks for some taxa, and therefore identifying and protecting hotspots should be a high priority in marine reserve design.

The concept of the ``wisdom of crowds'' has attracted attention for finding new insights by appropriately processing the large amount of information possessed by crowds. A prediction market is one estimating method that uses the mechanisms of financial markets such as stock or exchange markets to realize the ``wisdom of crowds''. In this study, we use agent-based simulation to clarify the condition that makes prediction markets effective. An artificial market is a virtual financial market run on a computer. Agents participate in them as computer programs that play the role of virtual dealers. In the simulation, we confirm the influence of the following parameters: information transmission frequency, the retention of motivation, and the gap of information recieve abilities. The results of this study suggest that prediction markets realize more accurate results than opinion polls under the following conditions: the gap of information recieve abilities and relatively low motivation.

Bacillus thuringiensis is a naturally abundant Gram-positive bacterium and a well-known, effective bio-insecticide. Recently, B. thuringiensis has attracted considerable attention as a potential biological control agent for the suppression of plant diseases. In this study, the bacterial wilt disease-suppressing activity of B. thuringiensis was examined in tomato plants. Treatment of tomato roots with B. thuringiensis culture followed by challenge inoculation with Ralstonia solanacearum suppressed the development of wilt symptoms to less than one third of the control. This disease suppression in tomato plants was reproduced by pretreating their roots with a cell-free filtrate (CF) that had been fractionated from B. thuringiensis culture by centrifugation and filtration. In tomato plants challenge-inoculated with R. solanacearum after pretreatment with CF, the growth of R. solanacearum in stem tissues clearly decreased, and expression of defense-related genes such as PR-1, acidic chitinase, and β-1,3-glucanase was induced in stem and leaf tissues. Furthermore, the stem tissues of tomato plants with their roots were pretreated with CF exhibited resistance against direct inoculation with R. solanacearum. Taken together, these results suggest that treatment of tomato roots with the CF of B. thuringiensis systemically suppresses bacterial wilt through systemic activation of the plant defense system.

An oil palm fiber module has been developed to modify a down-flow hanging sponge (DHS) reactor module. The objective of the proposed system is to improve two existing DHS variants of post-treatment unit for UASB treating domestic wastewater, i.e. cube-type and curtain-type sponge as domestic wastewater treatment system for developing countries. This paper describes the potential of oil palm fiber-based DHS (PF-DHS) configuration for sewage treatment. Feasibility of the PF-DHS reactor was evaluated by conducting a six-month continuous operation using actual sewage as feed. The system has been verified to have an excellent organic removal performance achieving 67% of unfiltered COD removal, and nearly perfect SS removal at the HRT of 2 h. It was observed that the organic removal rate was approximately 2.64 kg COD/m3 per day. The result recommended that the proposed PF-DHS reactor would be a promising system to alter sponge-based DHS for domestic wastewater treatment system in developing countries.

A sensitive urinary biomarker for acute kidney injury (AKI) was investigated in beagle dogs with nephrotoxicity induced by gentamicin. Gentamicin sulphate at 25 or 50 mg/kg was injected (s.c.) for 9 days, and conventional urinalysis, ELISA assay of neutrophil gelatinase-associated lipocal (NGAL) in urine, blood chemistry, and pathological examinations were performed. The dog given gentamicin at 25 mg/kg only showed slight deposition of lysosomal granules in the proximal tubular epithelium of the kidneys without any other significant changes even though urinary NGAL was elevated on Day 10 (day of necropsy). In the dog receiving gentamicin at 50 mg/kg, increases in urinary NGAL were observed on Days 3 and 5, and absence of urination, marked increases in serum urea nitrogen and creatinine, enlargement and discoloration of the kidneys with marked necrosis, and swelling of proximal epithelium were observed. In conclusion, urinary NGAL is considered to be a candidate as a sensitive predictable biomarker of AKI in the gentamicin-induced nephrotoxicity model in dogs.

A four-month-old female Labrador retriever was brought to the Tokyo University of Agriculture and Technology Animal Medical Center for examination of its main symptoms of cough, tachypnea and exercise intolerance. Upon examination, the dog was found to have cyanosis and inadequate growth. Echocardiography revealed tetralogy of Fallot. Cardiac catheterization confirmed that the main pulmonary artery was completely occluded and that blood flowed from the aorta to the pulmonary artery. Accordingly, the animal was diagnosed with extreme tetralogy of Fallot.

Urea breath test (UBT) using an infrared spectral analyzer is widely used for non-invasive and rapid detection of gastric Helicobacter spp. in human, but not veterinary medicine. The main purposes of this study were to determine the reference range of the UBT in dogs and to evaluate its clinical usefulness. To address the first aim, 6 healthy laboratory beagles were subjected to UBT and upper gastrointestinal endoscopy. Gastric endoscopic biopsy samples from the antrum, corpus and fundus were examined for Helicobacter spp. by polymerase chain reaction (PCR) testing, rapid urease test (RUT), histology and cytology. Amoxicillin, metronidazole and omeprazole were given to infected dogs for 14 days, and dogs that became Helicobacter-negative were used to determine the reference range for UBT. To address the second aim, 32 canine patients underwent UBT before upper gastrointestinal endoscopy, and the sensitivity and specificity of UBT were calculated based on our newly determined reference range using PCR as the gold standard for detection of Helicobacter spp. Initially, all 6 laboratory beagles were infected in all gastric regions and became uninfected after eradication. The mean ± 2 SD UBT value after eradication was 0.6 ± 1.8‰, and the reference range for UBT was determined to be less than 2.5‰. UBT was completed successfully in 27 patients. Using our reference range, UBT displayed 89% (16/18) sensitivity and 89% (8/9) specificity, indicating that UBT was quite useful for the detection of gastric Helicobacter spp. infection in dogs.
