<jats:p><jats:bold>Objective:</jats:bold> In the current study, we explored the neural substrate for acute effects of guanfacine extended release (GXR) on inhibitory control in school-aged children with attention deficit hyperactivity disorder (ADHD), using functional near-infrared spectroscopy (fNIRS).</jats:p><jats:p><jats:bold>Methods:</jats:bold> Following a GXR washout period, 12 AD HD children (6–10 years old) performed a go/no-go task before and 3 h after GXR or placebo administration, in a randomized, double-blind, placebo-controlled, crossover design study. In the primary analysis, fNIRS was used to monitor the right prefrontal cortical hemodynamics of the participants, where our former studies showed consistent dysfunction and osmotic release oral system-methylphenidate (OROS-MPH) and atomoxetine hydrochloride (ATX) elicited recovery. We examined the inter-medication contrast, comparing the effect of GXR against the placebo.

However, in the <jats:italic>post-hoc</jats:italic> analysis, we observed significant change in the oxy-Hb signal in the right angular gyrus (AG) for inter-medication (one sample <jats:italic>t</jats:italic>-test, <jats:italic>p</jats:italic> &lt; 0.05, uncorrected, Cohen's <jats:italic>d</jats:italic> = 0.71).</jats:p><jats:p><jats:bold>Conclusions:</jats:bold> These results are different from the neuropharmacological effects of OROS-MPH and ATX, which, in an upregulated manner, reduced right PFC function in ADHD children during inhibitory tasks. This analysis, while limited by its secondary nature, suggested that the improved cognitive performance was associated with activation in the right AG, which might serve as a biological marker to monitor the effect of GXR in the ADHD children.</jats:p>

<jats:p>In the midst of globalization, English is regarded as an international language, or Lingua Franca, but learning it as a second language (L2) remains still difficult to speakers of other languages. This is true especially for the speakers of languages distantly related to English such as Japanese. In this sense, exploring neural basis for translation between the first language (L1) and L2 is of great interest. There have been relatively many previous researches revealing brain activation patterns during translations between L1 and English as L2. These studies, which focused on language translation with close or moderate linguistic distance (LD), have suggested that the Broca area (BA 44/45) and the dorsolateral prefrontal cortex (DLPFC; BA 46) may play an important role on translation. However, the neural mechanism of language translation between Japanese and English, having large LD, has not been clarified. Thus, we used functional near infrared spectroscopy (fNIRS) to investigate the brain activation patterns during word translation between Japanese and English. We also assessed the effects of translation directions and word familiarity. All participants’ first language was Japanese and they were learning English. Their English proficiency was advanced or elementary. We selected English and Japanese words as stimuli based on the familiarity for Japanese people. Our results showed that the brain activation patterns during word translation largely differed depending on their English proficiency. The advanced group elicited greater activation on the left prefrontal cortex around the Broca’s area while translating words with low familiarity, but no activation was observed while translating words with high familiarity. On the other hand, the elementary group evoked greater activation on the left temporal area including the superior temporal gyrus (STG) irrespective of the word familiarity. These results suggested that different cognitive process could be involved in word translation corresponding to English proficiency in Japanese learners of English. These difference on the brain activation patterns between the advanced and elementary group may reflect the difference on the cognitive loads depending on the levels of automatization in one’s language processing.</jats:p>

<jats:title>Abstract</jats:title><jats:p>The 2011 Tohoku earthquake and tsunami in Japan was an extraordinarily stressful incident that caused harmful psychological reactions, such as posttraumatic stress disorder (PTSD), among affected individuals. However, a proportion of exposed individuals experienced posttraumatic growth (PTG), characterized by a noticeable degree of personal strength, spirituality, life appreciation, perception of new possibilities in life, and enhanced relationships with others. Some researchers have argued that these positive reactions may be an illusory change related to coping with traumatic events. We examined trajectory patterns related to PTG Inventory (PTGI) subscales to elucidate the existence of both real and illusory growth regarding quality of life (QoL), utilizing group‐based trajectory models. Three online questionnaires were distributed at 6 months (<jats:italic>N</jats:italic> = 2,554; <jats:italic>M</jats:italic> age = 47.04 years, <jats:italic>SD</jats:italic> = 12.62), 12 months (<jats:italic>N</jats:italic> = 887; <jats:italic>M</jats:italic> age = 48.11 years, <jats:italic>SD</jats:italic> = 12.43), and 42 months (<jats:italic>N</jats:italic> = 560; <jats:italic>M</jats:italic> age = 48.86 years, <jats:italic>SD</jats:italic> = 12.25) postdisaster. Participants responded to items related to demographic characteristics, disaster experiences, posttraumatic stress symptoms, PTG, and QoL. Three main PTG trajectories emerged, characterized by growth, no growth, and illusory growth, with QoL as a time invariant covariate. Compared with the growth trajectory, the odds ratios (<jats:italic>OR</jats:italic>s) for no growth ranged from 2.27 to 5.04; for illusory growth, the <jats:italic>OR</jats:italic>s ranged from 2.09 to 4.67. To our knowledge, this was the first study to report growth trajectories related to PTGI subscales and their underlying differences in psychological mechanisms and processes following the 2011 Tohoku earthquake and tsunami.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Autism spectrum disorder (ASD) and attention‐deficit hyperactivity disorder (ADHD) are believed to share the symptom of neurocognitive dysfunction in executive functions. Regarding the components of executive functions, however, dysfunction of motor‐response inhibitory control in children with ASD remains unclear. Thus, using functional near‐infrared spectroscopy (fNIRS), we investigated whether putative inhibitory brain dysfunctions are applicable to children with ASD by adopting a go/no‐go task, which has robustly evoked activation in typically developing (TD) children but not in ADHD children. Twenty‐four ASD and 24 TD children underwent a go/no‐go task, and their cortical hemodynamics were assessed using fNIRS. Relative to TD participants, ASD participants showed reduced activation in the right inferior frontal gyrus and middle frontal gyrus (IFG/MFG) during go/no‐go tasks. The current finding suggests that hypoactivation in the right IFG/MFG during a go/no‐go task would serve as a potential biomarker for identifying children with ASD.</jats:p>

Postharvest fruits are susceptible to damage which eventually results in large product and financial losses. While abundant studies have been conducted to objectively index the severity of such damage, how consumers subjectively assess the severity of damaged apples has been understudied. Previous studies have indicated that consumers' aesthetic devaluation of product quality is reflected in estimated price. Thus, the current online questionnaire study was conducted to examine the effect of objectively indexed severity of damage on consumers' subjective price estimations. Four hundred thirty-nine consumers of apples were asked to estimate the market price for apples in photographic images of 1 or 3 "Orin" ("Golden Delicious" x "Indo") apples at 9 levels of severity of damage. A 2 (1- and 3-piece) x 9 (severity of damage) within ANCOVA with reference price as a covariate indicated significant two-way interaction between the number of apples and severity of damage on estimated price. Consequently, the 1- and 3-piece conditions were examined separately. The results of both analyses indicate a categorical rather than quantitative, continuous reduction in estimated price.

<jats:title>Abstract</jats:title><jats:p>The present study explored the possibility of generating a novel sensory evaluation instrument for describing comprehensive food palatability via its subdomains (rewarding, cultural, and informational) while keeping physiological factors constant. Seventy‐five Japanese participants were asked to taste cheese samples and to respond to a questionnaire that was developed to dissect the distinct subdomains of palatability. The subsequent factor analyses revealed that three major factors may serve as distinct subdomains of palatability: rewarding, cultural, and informational, although the informational factor was not sufficiently robust. Multivariate regression analysis on cheese samples with exactly the same ingredients but sold in different packages led to different comprehensive palatability ratings due to the contribution of the cultural, but not the rewarding, factor. These results suggest that palatability is not merely determined by the physical and chemical properties that are intrinsic to a food product itself, but also depends on psychological properties that can arise through interaction between humans and the food product. The current study presents the first experimental demonstration that palatability could be dissociated to its subdomains.</jats:p>

【目的】注意欠陥/多動性障害(Attention Deficit Hyperactivity disorder;ADHD)は、有病率が5～7%と報告される実行機能障害である。発症は就学前後(6歳前後)に多く、診断に至らず症状が遷延すると日常生活や就学後の学校生活において自尊感情の低下(二次障害)をきたすため、早期治療介入を要するが、客観的診断手法は確立されていない。このため、ADHDの脳機能不全の病態を検討するため、1970年以降には機能的磁気共鳴画像法(functional magnetic resonance imaging;fMRI)を代表とする脳機能イメージング研究が報告され、実行機能障害に関与する右前頭前野の活性低下がエンドフェノタイプの有力候補になりうるとする知見が確立しつつある。しかしながら、それらの報告は思春期から成人を対象とした検討であり、検査中の高い拘束性、検査時間の長さから、本疾患の発症年齢前後(6歳前後)に対する検討が不十分である。以上から、体動や難解な課題が困難など、小児が有するこれらの特徴に適応可能であり、早期診断や治療に役立つ補助的ツールとして利用可能なエンドフェノタイプを作成する目的で、機能的近赤外分光分析法(functional Near-Infrared Spectroscopy;fNIRS)を用いた検討を実施した。先行研究では、fNIRSを用いて、小児(7歳を含む)ADHDを対象とし、実行機能課題(Go/NoGo課題)遂行時に、右前頭前野の機能不全が、治療薬である塩酸メチルフェニデート(Methylphenidate, MPH)服用後に改善する様子を可視化し報告した。我々の作成した解析系は、小児ADHDにおいて検査が可能(検査離脱率0%)である事が証明されたが、今後の課題として、健常児との比較検討がない点や、MPHによる脳機能変化の評価に、プラセボ(Placebo, PLA)を用いた盲検化はされていない点などが挙げられた。以上の背景から、我々は先行研究で小児ADHDに対して実施したfNIRS解析系を用いて、健常児の脳機能評価、MPH服用前後のADHD児の脳機能変化を観察するために、二重盲検クロスオーバープラセボ比較試験を用いた検討を実施した。【方法】同意が得られた、16人のADHD児、右利き、知能指数が70以上を満たす6-13歳(8.8±2.2(mean±SD))の男児12名、女児4名に対し、プラセボ二重盲検法を用いて、MPH服用前後におけるGo/NoGo課題遂行中の大脳皮質の酸素化Hb値の変化をfNIRS用いて解析した。また、ADHD群と年齢、性別を統計学的に合致させた6-13歳(8.9±2.4(mean±SD))の対照群(男児10名、女児6名)16人が本研究に参加した。対照群は薬剤を介入せず1回のみ計測した。fNIRS解析中にGo課題、Go/NoGo課題を交互に提示(1ブロック)を合計6回実施した。刺激課題の解析指標は、Go/NoGo課題中のGo課題反応時間、Go課題正答率、NoGo課題正答率とした。全6ブロックの平均値を計算し、統計解析は、Student's t検定を用いた。対照群(薬物内服なし)とADHD群(薬物服用前、MPH服用後、PLA服用後)の比較、ADHD群内における比較では、MPH服用前後、PLA前後、MPH服用前後とPLA薬服用前後を比較した。なお、本研究は自治医科大学と国際医療福祉大学病院における倫理委員会の承認を得て実施した。【結果】行動解析結果では、対照群と比較し、MPH服用前ADHD群はNoGo課題正答率に有意な低下を示した。MPH服用後には有意差を認めなかった。ADHD群のMPH服用前後の比較では、服用後にGo課題正答率が改善したが、ADHD群におけるMPH服用前後の変化とプラセボ薬服用前後の変化について比較したが、有意な差を示す行動解析指標はなかった。脳機能解析結果では、対照群に比して、薬剤服用前のADHD群の右前頭前野の活性は、抑制課題中に低下し、MPH内服後に改善した。一方で、PLA内服後には改善しなかった。行動解析で有意差はなかった比較条件である、ADHD群におけるMPH服用前後とPLA薬服用前後の変化の比較検討では、fNIRS解析では、右前頭前野(右中、下前頭回)において有意差を認めた。【考察】作成したfNIRS解析は、6歳以上のADHD児において検査可能であり、右前頭前野の機能不全が、MPHにより回復する過程を可視化した。この解析系を用いたエンドフェノタイプは、行動解析結果よりも統計学的に頑健な解析系であり、小児ADHDにおける早期診断や治療のための補助的手法として臨床の現場で貢献可能と考えられた。(本論文の内容は、学会発表後に受理となったの研究に基づき、内容を再編成したものである。)(著者抄録)

Several studies have reported that experts outperform novices in specific domains. However, the superiority of experts in accuracy, taking both trueness and precision into consideration, has not yet been explored. Here, we examined differences between expert and novice performances by evaluating the accuracy of their estimations of physical concentrations of sodium chloride in solutions while employing a visual analog scale. In Experiment 1, 14 experts and 13 novices tasted 6 concentrations of the solutions until they had learned their intensities. Subsequently, they repeatedly rated the concentration of 3 other solutions in random order. Although we did not find a difference between the performances of the 2 groups in trueness (difference between rating and correct concentration), the precision (consistency of ratings for each participant) of experts was higher than that of novices. In Experiment 2, 13 experts who had participated in Experiment 1 and 10 experts and 12 novices who had not participated in Experiment 1 rated the salt concentration in sodium chloride/sucrose mixtures in the same way as in Experiment 1. Both trueness and precision of performance were higher in both expert groups than in the novice group. By introducing precision and trueness parameters, we succeeded in quantifying the estimations of experts and novices in rating the concentration of solutions, revealing experts' superiority even for a task they had not been trained for. © The Author 2013.

目的 小児の注意欠陥多動性障害(ADHD)については、メチルフェニデート(MPH)内服による治療法が一般的に実施されているが、その薬理効果に対する適切な生物学的指標の確立はまだなされていない。近年開発と応用が進んだ機能的近赤外分光分析法(fNIRS)は、低拘束かつポータブルな無侵襲の脳機能イメージング法であり、MPH投与に対する脳機能変化の評価が行える可能性が高い。そこで、本研究では、ADHDの典型的症状である衝動性や注意力の制御に関わる抑制機能を反映するGo/NoGo課題遂行時の脳血流動態変化を、MPH内服前後でfNIRSを用いて評価することが可能であるかどうかを検討した。方法 親及び本人からICを得た、DSM-IV-TRでADHDの診断基準を満たした、右利き、平均9.5歳(7～14歳)、WISC-IIIでIQ>70以上の小児12例を対象とした。MPH(18～45mg)服用前後(1.5時間)で、Go/No-go課題遂行中にfNIRS計測を10分間実施した。NIRS計測は22チャネル(ch)のETG-4000(日立メディコ製)を使用しoxy-Hb信号を解析に用いた。本研究は、大学の倫理委員会の承認を得て実施した。結果 MPH服用後でNoGo課題の正答率は有意に上昇した。fNIRS計測においては、MPH内服前後で、右中前頭回/下前頭回の境界領域において、有意なoxy-Hb信号の上昇が観察された。課題正答率の上昇とoxyHb信号の上昇には有意かつ高い相関が認められた。結論 右前頭前野外側部は、ADHDによる抑制機能不全に関与する領域と考えられており、本研究の観察は妥当なものと考えられる。今回の計測は、3時間以内かつ1日の通院で実施可能であり、ADHD時におけるMPH投与効果について生物学的指標を用いて客観的に確認する上で、有用な手法と考えられる。(著者抄録)

ダイズの連作障害におけるアレロパシーの関与について調査するため，ダイズの無作付け土壌および1，2，3，5年作付けした土壌にレタスを播種し，バイオアッセイを行った．その結果，ダイズを1年以上作付けした土壌には，レタス幼苗に対する生育阻害活性が認められた．その際，活性炭添加による生育回復効果はダイズの連作年数の増加により小さくなり，土壌の生育阻害活性は，連作年数が増加するに従い上昇するものと考えられた．また，根圏土壌の理化学性について調査したところ，ダイズを作付けした根圏土壌には，塩類の集積やpHの変動，無機養分の異常あるいは病害の発生が認められなかった．従って，ダイズの連作障害の一因としてアレロパシーの関与が考えられた．この結果を踏まえ，アレロパシー物質の吸着効果を有する活性炭の，マメ類連作圃場への施用がダイズの生長に及ぼす影響について，「タチナガハ」，「エンレイ」，「玉大黒」，「小真木ダダチャ」および「夏の声」の5品種を用いて調査した．「タチナガハ」，「玉大黒」および「夏の声」では，活性炭の施用により，収量性の低下が軽減された．

<jats:p><jats:bold>Abstract: </jats:bold> The effect of sensory and extrinsic attributes on consumer intentions to purchase the Japanese traditional fermented soybean product <jats:italic>natto</jats:italic> was evaluated using conjoint analysis. Six attributes with 2 levels each were chosen and manipulated: price (high compared with low), the country of origin of the soybeans (domestic compared with imported), stickiness (strong compared with moderate), smell (rich compared with moderate), attached seasonings (attached compared with no attached seasonings), and the environmental friendliness of the packaging (high compared with low). A fractional factorial design was applied and 8 hypothetical product labels were produced. A sample of 479 Japanese housewives ranked these product labels based on their purchase intentions. Overall purchase intention was affected by country of origin, attached seasonings, and price; those attributes accounted for 81.0%, while the sensory attributes of the product accounted for 19.0% of purchase intents. In order to estimate market segments for the <jats:italic>natto</jats:italic> products based on consumer preference, a cluster analysis was performed. It identified 4 segments of consumers: 1 oriented to attached seasonings, another conscious of the price, and the other 2 oriented to origins.

日本の寒冷地において，近年，作付けが増えているムラサキアスパラガスは，定植後の若年株の収量がグリーンアスパラガスに比べて著しく劣ることが問題となっている．そのため，露地長期どり栽培での密植栽培による増収の可能性を，1999～2005年までの7年間にわたり調査した．その結果，ムラサキアスパラガス‘Purple Passion’の収量は，若年株ではグリーンアスパラガス‘UC157’に比べて低かったものの，密植栽培を行うと，‘UC157’の慣行区に近い収量を得ることができた．さらに，‘Purple Passion’の密植栽培の4年株以降では，‘UC157’の慣行区と同等の収量を得ることができた．また，‘UC157’と比較して，‘Purple Passion’は単位面積当たりの収穫本数は少ないものの，密植を行っても1茎重は維持された．このことから，収穫作業における労働負担軽減の可能性が考えられた．以上より，ムラサキアスパラガスは，グリーンアスパラガスと比べて密植栽培適性に優れていると考えられた．<br>

アスパラガスの収穫後の外観，重量およびアスコルビン酸含量の変化に対する品種および保存温度の影響を露地圃場にて春どりした‘UC157’，‘Gijnlim’および‘Purple Passion’を用いて調査した．また，青果物の品質低下と密接に関連する呼吸速度の差異についてもあわせて調査した．収穫直後において，‘Gijnlim’は他の 2 品種に比べて若茎頭部が緩く，アスコルビン酸含量が最も高かった．5，10 および 15℃ で 4 日間保存した後の品質を調査した結果，若茎頭部の開きの進行程度に対する保存温度の影響は小さかったものの，いずれの温度においても‘Gijnlim’でやや大きく，‘Purple Passion’で小さい傾向がみられた．一方，切り口の変色程度は，いずれの品種においても保存温度の上昇にともない大きくなったが，‘Gijnlim’のみが 10℃ 以上から急激に大きくなる傾向を示した．重量およびアスコルビン酸含量の減少は，いずれの温度においても‘Gijnlim’で他の 2 品種と比べて大きかった．また，収穫 2–8 時間後における呼吸速度（CO₂ 生成速度）についてみると‘Purple Passion’は，‘UC157’および‘Gijnlim’と比較し低い傾向にあった．以上より，アスパラガスの品質およびその収穫後の変化には品種間差異があることが明らかとなった．また，‘Gijnlim’は‘UC157’および‘Purple Passion’と比べて，品質劣化しやすい可能性が考えられた．そのため，春どりされる‘Gijnlim’の流通においては，温度管理や包装などを厳密にする必要があると思われた．<br>

Objective: To evaluate psychometric properties and comparability ability of the Montgomery-Åsberg Depression Rating Scale (MADRS) vs. the Quick Inventory of Depressive Symptomatology-Clinician-rated (QIDS-C16) and Self-report (QIDS-SR16) scales to detect a current major depressive episode in the elderly. Method: Community and clinic subjects (age ≥60 years) were administered the Mini-International Neuropsychiatric Interview (MINI) for DSM-IV and three depression scales randomly. Statistics included classical test and Samejima item response theories, factor analyzes, and receiver operating characteristic methods. Results: In 229 elderly patients (mean age = 73 years, 39% male, 54% current depression), all three scales were unidimensional and with nearly equal Cronbach α reliability (0.85-0.89). Each scale discriminated persons with major depression from the non-depressed, but the QIDS-C 16 was slightly more accurate. Conclusion: All three tests are valid for detecting geriatric major depression with the QIDS-C16 being slightly better. Self-rated QIDS-SR16 is recommended as a screening tool as it is least expensive and least time consuming. © 2010 John Wiley & Sons A/S.

The clinician-rated, 16-item Quick Inventory of Depressive Symptomatology (QIDS-C16) has been extensively evaluated in patients with major depressive disorder (MDD). This report assesses the psychometric properties of the QIDS-C16 in outpatients with bipolar disorder (BD, N = 405) and MDD (N = 547) and in bipolar patients in the depressed phase only (BD-D) (N = 99) enrolled in the Texas Medication Algorithm Project (TMAP) using classical test theory (CTT) and the Samejima graded item response theory (IRT) model. Values of coefficient alpha were very similar in BD, MDD, and BD-D groups at baseline (α = 0.80-0.81) and at exit (α = 0.82-0.85). The QIDS-C16 was unidimensional for all three groups. MDD and BD-D patients (n = 99) had comparable symptom levels. The BD-D patients (n = 99) had the most, and bipolar patients in the manic phase had the least depressive symptoms at baseline. IRT analyses indicated that the QIDS-C16 was most sensitive to the measurement of depression for both MDD patients and for BD-D patients in the average range. The QIDS-C16 is suitable for use with patients with BD and can be used as an outcome measure in trials enrolling both BD and MDD patients. Copyright © 2009 John Wiley & Sons, Ltd.
