第4次尾瀬総合学術調査の一環として,尾瀬ヶ原泥炭土壌の物理化学的性状と植生土壌生態系の窒素・リン動態の調査が尾瀬湿原39地点で行われた(2017年7月~2018年8月).泥炭土壌は水飽和状態に近く,弱酸性で,河川流路に近いヤチヤナギが高密度に分布するバンクホロー複合体の湿原凹地では,土壌の可給態リン量が多く,NO3-量,窒素代謝活性と酸化還元電位,および可給態リン量が水位変化と密に関連していた.下田代の湿原凹地のヤチヤナギ窒素固定活性の調査から,ヤチヤナギの窒素固定量と樹高の間に有意な相関関係が見出された.土壌の窒素・リン量とヤチヤナギの分布パターンとの関係の検討により,河川洪水氾濫水により湿原に運ばれたリンの湿原凹地への沈積が,ヤチヤナギ増殖活発化を招いたと推論された.葉生産から出発し,落葉の分解無機化,土壌中の微生物活動による窒素固定と脱窒,ヤチヤナギの根粒微生物による窒素固定を経て,植物体再生産に至る窒素循環の量的検討により,尾瀬ヶ原の植物土壌システムの窒素収支は,降水に伴う窒素供給を含めると,ほぼ植物葉の生産を賄うことが示された.この窒素収支の検討から,洪水に伴う外部からの窒素負荷増加は,植物生産増加をまねく可能性が示された.今後,河川洪水に伴う窒素・リンの尾瀬ヶ原湿原への供給と流出を含めた尾瀬ヶ原の土壌・植生システムの窒素,リン動態のさらなる詳細な量的調査が必要とされる.

According to the increasing interrelations between Japan and the other countries, it has become urgent necessity for the promising youth to acquire the ability to use English as acommunication means. Even in this Educational Faculty, most students expect to have language training for communication as well as lectures of the English literature or the English language. The present writer has introduced into classes the hearing lessons using English programs by shortwave broadcasting, such as Voice of America, or Radio Japan, etc.Through broadcasting, we can get large amount of various information in a short period of time. Students are compelled to concentrate their energies to listening to the English programs.As teaching material, English news has a merit to attract the student's attention easily, because it is closely connected with their general concerns. This paper states the significance of the training method of this hearing lesson and the way how to introduce it to the university students.

Although there are some newly-developed options to treat dystonia, its medical treatment is not always satisfactory. Zolpidem, an imidazopyridine agonist with a high affinity to benzodiazepine receptor subtype ω1, has been reported to improve clinical symptoms of dystonia in some cases. We conducted an open-label study to assess the efficacy of zolpidem in 34 patients with primary dystonia patients, The Burke Fahn Marsden Dystonia Rating Scale (BFMDRS) scores in the patients were decreased from 7.2±7.9 to 5.5±5.0 after zolpidem therapy (P=0.042). Next we evaluated 55 patients with primary and secondary dystonia, 16 of 55 patients (29%) responded to zolpidem, and secondary dystonia, particularly post-traumatic dystonia, was more responsive than primary dystonia (5 of 11 [46%] vs 11 of 44 [25%]). The efficacy of zolpidem was comparable to that of other oral medications in our previous study; 33 of 89 dystonia patients (37%) responded to trihexyphenidil, 13 of 53 (25%) responded to clonazepam, and 4 of 21 (19%) responded to baclofen. In conclusion, our large scale study suggested that zolpidem may be a therapeutic option for dystonia, particularly post-traumatic dystonia.

Various dietary protein supplements are used by the elderly and bedridden to maintain their skeletal muscle mass and functions. High-quality proteins act as an anabolic driver and help to improve muscle strength and performance. Previously, we reported that soy protein significantly attenuates denervation-induced loss of muscle mass and myofiber cross sectional area in mice with inhibition of ubiquitination and degradation of IRS-1 in tibialis anterior muscle. It also increased muscle volume and strength in bedridden patients. In the present study, we investigated the effects of dietary soybean supplementation on muscle functions in taxi drivers lacking vigorous physical exercise. We conducted a case-control study on 25 healthy, male taxi drivers between the ages of 36 and 71 y performing minimal physical exercise. They were divided into two dietary groups: the soybean diet group (n=13) who ate daily meals (dinner) supplemented with 50 g of steamed soybean for 30 d and the control diet group (n=12) who received no soybean supplement. Next, we measured the muscle cross-sectional area (CSA) and muscle strength and function in both the groups before and after 30 d of soybean intake. The body weights of both diet groups did not differ significantly over time. However, after 30 d of soybean supplementation, the soybean-fed group developed significantly higher muscle CSA and grip strength compared to the control groups. In conclusion, dietary soybean supplementation improved muscle function in taxi drivers who lacked exercise.

By developing Automatic Identification System (AIS), vessel positioning and detailed movement can be understood in real time. Although vessel movement data including AIS have been conventionally utilized in suspicious vessel detection, collision avoidance, and vessel trajectory analysis, etc., this study focuses on the new application fields of vessel movement data including logistics, shipping, shipbuilding, environment, and cruise industry. In this paper, description of AIS data and literature review of each field are first summarized, then the results of the questionnaire survey to the industry and application service of AIS data are analyzed. Finally, the future prospects of research and application to the industry in the fields that the authors focus are summarized.

Both MALDI and ESI are well-known ionization method which have been worthy of remark among mass spectrometrists. FTMS is a mass analyzer which can be used for each ionization method with very high mass resolving power and mass accuracy. Here we introduce some MALDI/FTMS and ESI/FTMS spectra with the new topics among the FTMS users. The new topics include SORI (Sustained Off-Resonance Irradiation) and QE (Quadrupolar Excitation) techniques.

Chronic kidney disease (CKD), marked by a progressive loss in renal function, is a leading cause of hemodialysis initiation and cardiovascular disease (CVD). There are currently 13.3 million patients with CKD and 300 thousand patients are currently undergoing hemodialysis in Japan. Therefore, preventing the initiation of dialysis and reducing the risk of cardiovascular death are high-priority issues from the viewpoint of public health and economic implications. Understanding the molecular mechanism responsible for the progression of CKD and cardiovascular damage regarding crosstalk between the kidney and cardiovascular system is an important issue in controlling the pathogenesis of CKD-CVD. However, the mechanisms involved in CKD-CVD are not well understood. This hinders the development of new treatment strategies. We have been investigating the role of protein bound uremic toxins, that are difficult to remove by hemodialysis, on the onset and progression of CKD and CVD. The relationship between their redox properties and the pathogenesis of CKD-CVD was examined. In this review, we focus on two sulfate conjugated uremic toxins, namely, indoxyl sulfate (IS) and p-cresyl sulfate (PCS), and summarize recent studies that provide new insights on the molecular mechanisms responsible for uremic toxin-induced oxidative tissue damage via a cardiovascular-renal connection.

先進運転支援システムや自動運転の実装により環境の変化が非常に加速している自動車業界では,車載システムの柔軟性や再利用性が求められるようになってきた.それらをサポートするため,サービス指向通信ミドルウェアである SOME / IP (ScalableService-Oriented MiddlewarE over IP) の標準化が進められている.車載ネットワークの通信ミドルウェアに対する性能要件として,サービスの利用確立までの遅延や,通信メッセージのリアルタイム性などがある.サービス指向はサービスをネットワーク上で連携させてシステムの全体を構築していくため,動的なネットワークの設計を行う必要がある.従来,静的にネットワーク設計を行っていた車載システムに比べてオーバーヘッドが増加することは明らかである.本研究では,SOME / IP の Service Discovery における通信確立遅延を測定し,考察する.
