立体規則性高分子の単結晶において,分子鎖間に「分子キャビティー」と呼ばれる空孔が生成する系があり,その構造を制御することにより,特定の分子を分離・回収する高性能な分離膜としての利用が期待されている.分子キャビティーの構造を解明するために様々な研究が行われているが,複雑なキャビティーの構造を立体的・直観的に把握することは困難である.そこで,本研究では,3Dプリンターを用いてキャビティーの立体モデルを作成することで,構造の理解を深めることを目的とする.分子キャビティーを持つシンジオタクチックポリスチレン(s-PS)のδe型,ε型及びS-I型を対象として,分子動力学(MD)シミュレーションを行い,分子キャビティーの構造を再現した.得られたデータを3Dプリンターで利用可能な構造データに変換し,分子キャビティーの立体造形モデルを作成した.δe型について,b軸方向及びac軸方向につながるチャネルを再現したところ,気体分子が拡散しやすいac軸方向につながるチャネルの方が太くて短い様子が十分に再現されていた.一方ε型とS-I型については,それぞれ,円筒型とジグザグ状のチャネルが得られた.さらに,これらのモデルに気体分子を挿入した系について解析を行い,気体分子が跳躍運動をしている瞬間を3Dモデル化することにより,結晶構造と気体の拡散様式の関係を直観的にとらえることに成功した.

Central neurotransmitter and/or neuromodulator candidates reported to affect gastric acid secretion are: (excitatory) acetylcholine, thyrotropin releasing hormone, GABA, oxytocin; (inhibitory) noradrenaline, adenosine, bombesin, calcitonin-gene related peptide, corticotropin releasing factor, beta-endorphin, neurotensin, neuropeptide Y, insulin-like growth factor II and prostaglandins. Regulation of gastric acid secretion by central administration of these substances in experimental animals such as rats and dogs are briefly reviewed, and central inhibitory mechanisms of this function are discussed based on our studies with noradrenaline and bombesin. Roles of hypothalamic nuclei such as the ventromedial nucleus and the lateral hypothalamus in regulation of autonomic nerve activities are also described as an introductory note.

Tomato plants were grown with a drip irrigation system to evaluate the effects of a novel organo-mineral fertilizer [2:10:1 (w/w/w) mixture of calcium sulphate, ground rice bran, and humic acid] (OMF), which can mitigate salinity stress, on plant growth, fruit yield, and the incidence of blossom-end rot (BER) under salinity stress. Salinity stress was applied by drip irrigation with 50 mM of NaCl. Plant growth with OMF was lower than that with chemical fertilizer (CF). Higher levels of K and P were obtained in the leaves from plants grown with OMF. OMF inhibited Na accumulation and proline increase in the leaves and was considered to alleviate salinity stress. Salinity treatment caused a decrease in fruit weight and an increase in ascorbic acid, sucrose, glucose, fructose, and glutamic acid. Tomato plants grown with OMF had smaller fruit than with CF without salinity, but the incidence of BER under salinity was reduced by OMF. The water soluble Ca content of the distal half of young tomato fruit was significantly decreased with salinity treatment. The incidence of BER under salinity was significantly lower in OMF than in CF, but there was no difference in the concentration of every form of Ca between CF-salinity and OMF-salinity treatments. The reduction in BER incidence with OMF treatment could not be explained by the differences in Ca concentration. The mechanism of the reduction in BER with OMF was not clear, so further studies are necessary.

Changes in light quality strongly affect several plant anatomical, physiological, morphological, and biochemical parameters of orchid tissue culture seedling growth. In this experiment, ways in which light quality influence plant photosynthesis, growth parameters, and carbon dioxide rhythms of different sizes (stage I, II, and III) of Phalaenopsis tissue culture seedlings were examined. Stage I (Seedlings of 1–2 cm in height with 1–2 leaves and 1–2 roots) tissue culture seedlings were grown under six different light qualities under a T5 fluorescent lamp: White, Red (610 nm), Red (658 nm), Blue (440 nm), Red (610 nm) + Blue (440 nm), and Red (658 nm) + Blue (440 nm). After 5 months, cultured seedlings exposed to the Blue (440 nm) treatment showed significantly higher responses in terms of leaf quantities and chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid content. On the other hand, seedlings subjected to the Red (658 nm) treatment grew more stems and presented with higher fresh weight and leaf lengths compared to the results of other treatments. The number of roots increased under the Red (658 nm), Blue (440 nm) + Red (610 nm), and Blue (440 nm) + Red (658 nm) treatments. Moreover, seedlings subjected to Red light (658 nm) showed significantly higher levels of Rubisco enzyme activity than those subjected to the other treatments. Phosphoenolpyruvate carboxylase activities recorded during the nighttime in seedlings subjected to Red light (658 nm) were also significantly greater. The results showed that during stage I, the concentration of carbon dioxide rhythm ranged from 1500–1800 ppm and reflected a C3 photosynthesis system. As the seedlings matured, the carbon dioxide rhythm decreased to 400–800 ppm at night and reached stage III (CAM plant). After 5 months of culturing, the carbon dioxide rhythm of the Red (658 nm) treatment seedlings changed from C3 to CAM, while seedlings subjected to the other treatments were still in the intermediate stage (stage II). From these results, we conclude that to enhance seedling growth through commercial production, Red (658 nm) should be applied.

私たちは自分のコミュニケーションスタイルを用いて他者とのコミュニケーションを行っているため,一般的には人間間のコミュニケーションには性格によっておおよそ決定された相性が存在する.本研究では,性格を付加した擬人化エージェントを開発し,人間と擬人化エージェント間のコミュニケーションの相性が存在するかを検証した.また,人間と擬人化エージェント間のコミュニケーションが人間間に適用される法則に当てはまるかを調査した.その結果,人間と擬人化エージェントの性格によるコミュニケーションでは,人間間の相性として知られるフックの法則とは異なり,人間と擬人化エージェントでの新たな相性が存在することが示唆された.

A wealth of evidence has indicated that an abundance of negative biases and a lack of positive biases in memory could be an important factors in the onset and subsequent maintenance of depression. Moreover, recent studies have suggested that attentional biases influence memory biases and biases in the information input stage might play a key role in causing these biases. Nevertheless, most studies on memory biases have investigated only recall biases, with only a few studies directly examining encoding biases. Therefore the relationship between dysphoria and encoding biases was investigated using the recognition task described by Müller et al. (2009). Results indicated that encoding positive words enhanced encoding preceding and subsequent words in non-dysphoric participants, whereas this was not the case in dysphoric participants. These results suggest that dysphoria is associated with a paucity of encoding information presented temporally close to positive information. It is suggested that future studies should investigate the impact of processing emotional information on processing other types of information in people with depression.
