We compared the physiological activities of sesame seeds rich in lignans from three varieties (Gomazou, Maruhime and Maruemon), and those from a conventional cultivar (Masekin) in rats. The sum of the values of fat-soluble lignans (sesamin and sesamolin) in seeds of Gomazou, Maruhime and Maruemon varieties was approximately double the value in Masekin. Seeds from Maruemon contained fat-soluble lignan most exclusively as sesamin while other varieties contained sesamin and sesamolin at about a 2:1 ratio. After a 16 d experiment, sesame seeds, added at 200 g/kg to the experimental diets, increased the activity and mRNA levels of fatty acid oxidation enzymes. Increases were stronger with seeds rich in lignans than with seeds from Masekin. In contrast, sesame seeds lowered the activity and mRNA levels of lipogenic enzymes. However, sesame seeds from all the varieties were comparable in affecting these parameters. Serum triacylglycerol concentrations were lower in rats fed diets containing sesame seeds rich in lignans than in those fed a diet free of sesame seeds or a diet containing seeds from the Masekin variety. Serum malondialdehyde (a marker of lipid peroxidation) was lower in rats fed diets containing sesame seeds rich in lignans than in those fed a sesame seed-free diet or Masekin diet. It is apparent that sesame seeds rich in lignans, irrespective of lignan composition, more profoundly affect hepatic fatty acid oxidation and serum triacylglycerol levels and possibly attenuate oxidative stress. Therefore, consumption of sesame seeds rich in lignans hopefully results in physiological activity to promote health.

近年発表されたイシサンゴ類の分子系統解析の結果および詳細な形態解析を基に,2012年にAnn Budd博士らによって,オオトゲサンゴ科およびキクメイシ科の分類体系の改変が行われた。この改変では,大西洋産のオオトゲサンゴ科およびキクメイシ科を独立した科として扱うこととし,それに伴い太平洋産の両科およびいくつかの属も改編される運びとなった。特に,これまで一般的に良く利用されていた科であるMussidaeやFaviidae,さらに属のFaviaやMontastraeaが大西洋限定となったために,これらの科および属名の変更が行われた。そのため,今後の論文投稿でもかなりの混乱が予想される。そこで本稿では,これらの改変された理由および現時点での改変をまとめた。

Human respiratory syncytial virus (hRSV) is the most common cause of bronchiolitis and pneumonia in infants. The lack of proper prophylactics and therapeutics for controlling hRSV infection has been of great concern worldwide. Xylitol is a well-known sugar substitute and its effect against bacteria in the oral cavity is well known. However, little is known of its effect on viral infections. In this study, the effect of dietary xylitol on hRSV infection was investigated in a mouse model for the first time. Mice received xylitol for 14 d prior to virus challenge and for a further 3 d post challenge. Significantly larger reductions in lung virus titers were observed in the mice receiving xylitol than in the controls receiving phosphate-buffered saline (PBS). In addition, fewer CD3+ and CD3+CD8+ lymphocytes, whose numbers reflect inflammatory status, were recruited in the mice receiving xylitol. These results indicate that dietary xylitol can ameliorate hRSV infections and reduce inflammation-associated immune responses to hRSV infection.

本研究は, 窒素追肥がダイズにおける過湿障害の軽減に有効か否かを知るために行った. まず, 水田転換畑でダイズ品種タマホマレを栽培し, 花芽分化期に畦間に5~8cmの深さに水を溜めて8~11日間過湿処理を行い, 過湿処理終了後に硫安を窒素成分で12gm-2追肥した. 過湿・無追肥区における子実収量は無過湿・無追肥区に対して20%低下したが, 窒素追肥を行った過湿・追肥区では, 6%の低下に留まった. これは, 莢数減少の度合が軽減されたことに起因した. 次に, 窒素追肥によって莢数減少の度合が軽減されるメカニズムについて調べた. 水田土壌を充填したポットにタマホマレを栽培し, 花芽分化期に地下水位が5~7cmとなるようにポットを水槽につけた湿潤区, 地上水位が2~3cmとなるようにした湛水区, ならびに適宜灌水した適湿区を設け, 7日間の過湿処理終了後に, 各区のポットの半数に硫安をポット当り5g追肥した. 湿潤・無追肥区と湛水・無追肥区では, 葉身窒素含有率の減少が光合成速度の顕著な低下を招いたが, 窒素追肥をした湿潤・追肥区と湛水・追肥区では, 全窒素同化量が増大し, 葉身窒素含有率が上昇して光合成速度が増大した. 光合成速度の増大 (光合成産物の増大) は, 花器脱落の抑制をもたらし, その結果莢数減少の度合が軽減されたものと考えられた. 以上のように, 花芽分化期に過湿処理をしたダイズに窒素追肥を行ったところ, 子実収量の減少が軽減されたが, これは光合成速度増大による花器脱落の抑制に起因したと考えられた.

The supplementation of food products with iron is a useful approach to redressing its inadequate intake in many populations. The iron-lactoferrin complex (FeLf) is a common food ingredient because of its iron solubilizing capability in the presence of hydrogen carbonate ions. FeLf is a useful food product for iron and lactoferrin fortification, preventing anaemia with no risk of toxicity. This review focuses on the recent advances in FeLf regarding the structural features of the complexiation of FeLf, the thermal stability of FeLf in the applications to food products, and the suppressing effect of FeLf on the iron-catalysed off-flavor formation. The findings also encompass the beneficial effects on central nerve system, such as mental stress and the subjective symptoms associated with menstruation. The research stream of FeLf provides the beneficial findings in applications of FeLf to foods and neutraceuticals.

妊娠期の母親の栄養摂取状態は、子どもの成人期の健康状態に影響を及ぼす。母親のエネルギー摂取が不足すると血糖値およびコレステロール濃度が高値を示した。また、高脂肪食では低メチル化遺伝子が4%多く、肝臓の遺伝子発現は増加し、エネルギー制限では超高メチル化遺伝子が25%増加し、肝臓の遺伝子発現が低下していると考えられた。したがって、胎児の遺伝子発現に母親の栄養摂取が過剰であっても、また欠乏しても影響を与えることが明らかになった。

The emergency situation during flight causes the typical stress reactions for flight crew and passengers due to its sudden onset, urgent risk for life, long duration, sophisticated counteract and abrupt workload increase. However, the probabilistic risk is theoretically assessed on its designing stage. The detereoration of mental and behavioral pattern under emergency is categorized as the results of investigations of bailed-out accidents of fighter aircraft. Also, the reliability of behavior in critical situation is discussed in comparison with data obtained from nuclear plant operators. Voice analysis of communication and heart rate variability are the useful indicators to estimate the grades of stress reaction during flight. Tree different levels of human information processing should be considered in the emergency training for flight crew. Crew coordination is also the essential factor in emergency situation.

The purpose of the present study was to clarify the influence of swing parameters by changing the hitting point in space in baseball batting. Twenty-eight skilled baseball players (12 professional and 16 universitylevel) participated. The participants were instructed to hit a ball that was tossed from 5 m away in the direction of the pitching mound. The balls were tossed to various locations with reference to the home plate. The participants were required to hit the balls in a specific direction according to the tossed course, i.e., a ball tossed to the inside of a home plate was stroked toward the same-field direction and one tossed outside of the home plate was stroked toward the opposite-field direction. The motions of the ball and bat during these attempts were recorded using a motion capture system operating at 500 Hz. The 3D coordinates of the ball center (hitting point) and the swing parameters included the speed of the head of the bat (bat-head speed) and the angle of the swing from a horizontal line (swing angle) measured immediately before ball impact and the time from the start of the swing to ball impact (swing time). These parameters were calculated in each trial. Analysis of a total of 644 trials revealed that the bathead speed tended to increase as the hitting point moved inside, forward, and low. Furthermore, the swing angle and swing time tended to increase as the hitting point moved inside, forward, and high. Stepwise multiple regression analysis demonstrated that the bat-head speed and swing angle were independently associated with (in the following order) the distance in the pitcher’s direction, the hitting height, and the inside-outside direction course (R2=.360 and R2=.589, respectively). These results suggest that the timing of swing initiation and bat acceleration during a swing motion are the main factors changing the swing parameters, and that in order to sharp hit a ball, it is important to impact the ball with the hitting point as close to the pitcher as possible.

The purpose of this research was to investigate an attention restorative effect in the short-term staying of the on-site forest environment, using PRS based on an attention restoration theory (ART). Participants were 45-male-university students in their early twenties. The city environments where were the daily living environment were chosen as the control for experiments and in which the same experiment of the forest environments were conducted by the same schedule. To cancel an order effect, participants were divided into two groups and both groups were taken to the both environment to experience each of them during two days. After an experience in the each environment was finished, participants were asked to answer to PRS questionnaire. As a result, the appraisal of "Preference" for the forest environment was significantly higher than for the city environment on the contrary to that of "Familiarity". Then, the score of the indexes ("Being away", "Fascination", "Scope", "Compatibility") derived from ART after the experience of the forest environment was significantly higher than that of city environment. Consequently, there was psychological restorative effect in forest environment comparatively, from the viewpoint of ART and their traits were confirmed.
