Conjugated linolenic acids (CLNs) are naturally occurring fatty acids that are believed to have anticancer properties. In this study, we examined various plant seeds from herbs to discover seed oils containing CLNs. The ultraviolet spectra of total lipids from these seeds were measured. An absorption maximum around 270 nm was observed in seed oils belonging to the Valerianaceae family (Centranthus ruber and Valeriana officinalis). When the fatty acid compositions of these seed oils were measured, CLNs were detected. By silica column chromatography, neutral lipids (NLs), glycolipids, and phospholipids were eluted from seed oils of C. ruber and V. officinalis. Then, fatty acid compositions of these fractions were measured. This revealed that most of the CLNs in these seed oils existed in the NL fraction. When the NL fractions of these seed oils were reacted with lipase, CLNs showed good sensitivity to lipase hydrolysis. This suggested that the CLNs in the seed oils of C. ruber and V. officinalis existed predominantly at the sn-1,3 position of triacylglycerol and less at the sn-2 position. These results suggested that the CLNs from the seed oils of C. ruber and V. officinalis could easily be taken up by cancer cells as free fatty acids and had good potential as antitumor substances.

わが国で発見されたKAは,マイコトキシンという言葉が使われだした10数年前からこの範ちゅうに入っているが,実験動物に対する毒性が弱く,これによる事故が報告されていないことから余り問題にされていなかった。近年突然変異原性を有することがAmes testで明らかにされたことより,現在わが国の発酵工業で使用されている麹菌の中よりAsp. oryzae(149株),実験室保存のAsp. flavus(46株),Asp. tamarii(9株)について,KAとAFの産生能を検討した。1. Rec-assay法を使用してKA,AFを含む13種のマイコトキシンのDNA作用を検討し,KAとAF-B1を含む7種が陽性であることを明らかにした。2. 供試菌204株についてAF産生能を試験した結果,Asp. oryzaeとAsp. tamariiの全供試菌株には産生が認められず,Asp. flavus46株中24に産生が認められた。3. KA産生能試験は,坂口培地を使用し,30℃,14日間培養し,培養液を硫酸第二鉄で呈色し比色定量した。Asp. flavusとAsp. tamariiの全供試菌は,KAを産生し,最高産量は40mg/ml培養液以上であった。Asp. oryzae149菌株中105株にKAの産生が認められ,残りの44株(約30%)に産生が認められなかった。

社会性行動は個体間の感覚運動的相互作用によって発達する。我々は社会的きずなの形成を神経行動学的に解析し,その分子的基盤を解明することを目指して動物モデル(家禽ヒヨコおよびマーモセット)を開発した。まず社会性行動を統合的・定量的に解析するための行動テスト法を確立し,テスト中の身体動画像から得られたパラメータの多変量解析により行動の質を評価する方法を開発した。ついで,社会的きずなの形成には,社会的相互作用が特に有効な時期(臨界期,高感受性期)が存在することを明らかにした。この時期に相互作用を体験しない個体におけるセロトニン,ノルアドレナリン作動性神経系の賦活効果を検討したところ,SSRI/SNRI が有効であったが,同時に臨界期後の社会性行動の“トレーニング”が必須であった。この結果は,本モデルが発達障害や他の精神疾患における社会性行動障害の病態モデルとして有効であることを示唆している。

Upon reviewing previous models for predicting regional development impact of transportation investment, the author shows that most of the notable models did not pay due attention to the concept of location rent, despite its potential usefulness and theoretical justification.The author presents interim results of a model currently being developed. In this model, location rent is considered to be a representative indicator of accessibility to various opportunities. On the basis of actural interregional flow data of commodities, location rent has been derived, and its consistency with the observed land value has been tested. The results are a partial success. The derived location rent has been confirmed as an explanatory variable of the land value. But, it has also been shown that agglomeration has an overwhelming impact on land value.

During fiscal year 2010, I. hospital changed its educational modality for new nurses from conventional classroom education to participatory education using an e-learning. Results show that 1) new nurses became able to learn anytime and anywhere. 2) Irrespective of the time and place, senior nurses became able to give advice related to questions and problems that new nurses had encountered according to a specific scenario. 3) The new-nurses training program which utilized e-learning based on the image showed the effect to the new nurse technical acquisition also from the result of the skill test and the interview.

BackgroundCognitive dysfunction has been recognized as a diabetes-related complication. Whether hyperglycemia or elevated fasting glucose are associated with cognitive decline remains controversial. We aimed to investigate the relationship between fasting glucose levels and cognitive function in diabetic and non-diabetic individuals.MethodsParticipants were Japanese diabetic (n=191) and non-diabetic (n=616) men, aged 46-81 years, from 2010-2014. Blood samples were taken after a 12h fast. Cognitive Ability Screening Instrument (CASI), with a maximum score of 100, was used for cognitive assessment. Cognitive domains of CASI were also investigated. Fractional logit regression with covariate adjustment for potential confounders was used to model cross-sectional relationships between fasting blood glucose and CASI score.ResultsFor diabetic individuals, CASI score was 0.38 (95% confidence interval: 0.66-0.12) lower per 1mmol/L higher fasting glucose level. Short-term memory domain also exhibited an inverse association. For non-diabetic individuals, a reverse u-shaped relationship was observed between fasting glucose and cognitive function, identifying a threshold for highest cognitive performance of 91.8 CASI score at 3.97-6.20mmol/L (71.5-111.6mg/dL) fasting glucose. Language ability domain displayed a similar relationship with fasting glucose.ConclusionsElevated fasting glucose levels in diabetic men were associated with lower cognitive function, in which short-term memory was the main associated domain. Interestingly, in non-diabetic men, we identified a threshold for the inverse relationship of elevated fasting glucose with cognitive function. Contrastingly to diabetic men, language ability was the main associated cognitive domain.
