 I participated in FEMS 2019 (8th congress of European microbiologists) on 7th-11th, July, which was held in Glasgow, Scotland. I also attended a mini-symposium hosted by Professor Riitta Korpela , Faculty of Medicine, University of Helsinki in addition to the tour at her laboratory.
 As the biggest city in Scotland, the third in the United Kingdom, Glasgow is a historic harbour city not only as a major center of Scottish Enlightenment in the eighteenth century but also as an economic center nowadays. It was a comfortable climate in July, the temperature was around 25℃ with lower humidity than Japan during the day. You can find historical buildings mainly in Glasgow Style and Victorian architecture. The apartment we lived in this time was one of a series of the red sandstone building and it seemed to be a typical european style of apartment in Glasgow. As walking through the city, I was feeling staying in a huge museum because there were so many historical train stations, ancient walls and old gorgeous restaurants. However, along the river Clyde, modern buildings also attracted my attention. The Scottish Exhibition Campus (SEC), in where FEMS 2019 was held, shaped like a metal UFO with several halls and meeting rooms. Glasgow is such a charming city with both historical and modern atmosphere.
  FEMS is held in European cities every two years and congresses are the only scientific meetings at European and international level providing discussion between all microbiological specialties. FEMS 2019 which we, Professor Haruki Kitazawa and postdoctoral fellow Dr. Aminul Islam, participated in this congress, was in collaboration with Society for Applied Microbiology (SFAM) and was a gathering of leading scientists in different fields of microbiology, together facing some of global challenges such as antimicrobial resistance, environment pollution and the emergence of pathogenic disease.
 On welcome reception on the first night, a co-worker of Dr. Aminul happened to attend the congress in coincidence. They talked about the research career these years and in the future. It felt to me amazing that friends who had not seen for many years could meet at a congress of microbiology because of science. I gave a presentation at the poster session on the second day of the congress. The title of my poster is “Selection of wakame assimilative lactobacilli and in vitro evaluation of their immunomodulatory potentials”. Although I was not worried about my English, as the first time to present at an international congress, I became nervous when I presented in front of strangers. However, Professor Kitazawa and Dr. Aminul kept telling me to calm down and be relaxed because I knew most of my poster than any of the others. Thanks to the advice and the practice, I was able to communicate with those who were interested in my research. I presented my poster in fluent English quite better than imagined. The main object of my research was wakame and lactic acid bacteria and I thought that wakame was known to everyone. Therefore, I did not prepare details about wakame. However, I realized that apparently, no one knew wakame in Europe because most of them who asked me questions started with “Can you tell me what is wakame?”. Things that are normally seen in daily life in Japan or Asia, maybe unique to the other side of the world. I wish I could have brought the real wakame to show everyone in this time.
 At the end of the poster session, there was a moment of regret that I wanted to say more about my research, but it was an unforgettable experience to introduce my research to the public in scientific English. It was an opportunity to improve my Scientific English speaking ability and also, knowledge of microbiology was broaden by attending lectures in different field and presentation by young researchers
 After FEMS 2019, Prof. Kitazawa and I attended a mini-symposium hosted by Prof. Riitta Korpela , Faculty of Medicine, University of Helsinki . Prof. Korpela’s lab was doing researches on lactic acid bacteria contained in a traditional fermented dairy product Viili, which had a part overlapping with my research. It was a great opportunity to know about the trend of fermented products in Finland and Europe and to consider future research on lactic acid bacteria during the symposium and warm discussions with students after each talk. After the symposium, Prof. Ritta Korpela showed us around her laboratory. I have learned more about a new lactobacilli strain from the young researchers of the same generation at the mini-symposium, which contributed to a great improvement in motivation for future research.
 Last but not least, I would like to express my sincere appreciation to all members of Suisei Nougaku Shinkoukai for the grant. It was a great opportunity to participate in an international conference like FEMS 2019.  I will try my best to make use of this experience and work harder in my research.



Indonesian Academic Trip (Asian Congress of Nutrition, University of Sebelas Maret, and Bakrie University)

Laboratory of Nutrition

 During last August 2019, I had a chance to visit my home country, Indonesia, as a part of the academic program from the Laboratory of Nutrition, Tohoku University. Totally, I visited three separated events or institutions including the Asian Congress of Nutrition (ACN) 2019 in Nusa Dua, Bali, the University of Sebelas Maret in Surakarta, and also Bakrie University in Jakarta.
 I started my trip by attending the Asian Congress of Nutrition (ACN) on August 4th-7th, 2019 in Nusa Dua, Bali, Indonesia. The ACN is the biggest four-year meeting for nutrition-related experts throughout the Asian continent. In the first day, August 4th, I attended the opening ceremony of ACN which was followed by the plenary presentation by Prof. Alfredo Martinez (President of International Union of Nutritional Society/IUNS) and Prof. Teruo Miyazawa (President of Federation of Asian Nutrition Societies/FANS). Prof. Alfredo Martinez gave a speech about nutrigenomics application for the precision of nutrition assessment, while Prof. Teruo Miyazawa gave a speech about food innovation using world-cutting edges technologies. The day after, August 5th, I joined the company symposium sessions held by FrieslandCampina Institute and DuPont. The topics of this symposium were about the balancing of protein using in early and later-stage of life and also the functional use of human milk oligosaccharides, respectively. Beside joining symposium, I also had a chance to present my recent work in an oral presentation session. In this meeting, I presented my work about the Vitamin K2 attenuates the lipopolysaccharide-induced inflammation in mouse microglial cells. In the following day, I attended the symposium held by the Japan Society of Nutrition and Food Science (JSNFS) about elderly nutrition and nutrition management during emergency and disaster. The speeches were given by Dr. Marthalena Purba from Indonesia, Dr Noriko Sudo and Dr Nobuyo Kasaoka from Ochanomizu University and National Institute of Health and Nutrition of Japan, respectively. I completed my ACN duty by attending some oral student presentation on the last day, August 7th.
 After ACN activity, I traveled to my home town in Surakarta, Indonesia to visit University of Sebelas Maret Surakarta. In this university, I had a chance to speak about my work in Japan. Again, I presented my research which had been published in the International Journal of Molecular Science titled “Menaquinone-4 Suppresses Lipopolysaccharide-Induced Inflammation in MG6 Mouse Microglia-Derived Cells by Inhibiting the NF-κB Signaling Pathway”. After the presentation, Dr. Danar Praseptiangga, the head of the department of food science and technology introduced me personally all the laboratory work and facilities in his department. Currently, the department of food science and technology, University of Sebelas Maret developed a new chocolate-based product. They did several types of research to optimize the production of chocolate but unfortunately, they still could not analyze the product physiological effect. The department of food science and technology, University of Sebelas Maret wish that in the near future, they can also do a nutrigenomic experiment in order to evaluate their product beneficial effect. Furtherly, they expected me to contribute in this collaboration in the near future.
 Before coming back to Japan, I had a chance to visit the department of food science and technology, Bakrie University in Jakarta. In this university, Dr. Ardiansyah, the head of the department gave me opportunity to share my experience regarding management of research in Japanese university. Interestingly, I did not only give speech but also received fruitful feedback because the audiences were some young and energic lecturers. They also shared their current work and gave their opinions about how to increase the quality level of research among Indonesian university. It was much interesting that we agreed to have a nice collaboration in the future so that we can make a better and higher quality of nutrition research in Indonesia.



International Symposium on Ruminant Physiology参加報告

資源生物科学専攻 動物生理科学分野
氏名:西原 昂来

 私は、2019年9月3日から6日にかけてライプチヒで開催されたInternational Symposium on Ruminant Physiology(ISRP)に参加しました。通常のAnimal Scienceの学会は、動物種は指定されることはなく、ウシ、ブタ、ニワトリなどに関する研究が同じ会場で発表されることが多いです。しかし、本学会は、ウシといった反芻動物のみに焦点を当てた珍しい学会です。そのため、反芻動物における生理学分野の学会としては、世界で最も規模のある国際学会ということが出来ます。
私は、学会2日目に「ルーメン上皮細胞のToll様受容体5(Roles of Toll-like receptor 5 ligand in the innate immune system in primary bovine rumen epithelial cells)」に関して口頭発表を行いました。国際学会で口頭発表するのは、二回目であるため、スライドを説明するのには問題がありませんでした。しかし、英語での質疑応答に非常に苦労しました。私の発表に関して、二名の方から質問があり、最初の一人からの質問には、何とか返答することができたのですが、二人目の質問を完全に理解できず、返答できませんでした。普段から英語でディスカッションする機会がなく、自身の準備不足を痛感しました。発表後に質問内容を確認すると、何となくニュアンスは合っていたので、これからは、細かいところまで聞き取れるようリスニングを鍛えたいです。また、卒業後は、海外でポスドクを経験して、英語でのディスカッションも難なく行えるようになりたいです。

The trip lasted for 24 days in total. It began in 2nd of August through a flight from Narita International Airport to a connecting flight in Kuala Lumpur International Airport, and to its final destination in Ngurah Rai International Airport in Bali, Indonesia. Arrived on August 3rd at 12.05 in Denpasar, it took around 45 minutes to get to Nusa Dua, where the Asian Congress of Nutrition 2019 was held. The first day consisted of checked in, re-registration at the front desk, and confirming the schedule for the next four days. The opening ceremony, exhibition and welcoming dinner were held on the next day. However, most of the symposiums, lectures and presentations were only started on the 5th of August, the next day. On this day I attended some event including those on the theme of biochemistry, cancer & holistic-body composition, and innovations in nutrients for health and wellness. My poster presentation, on the title of “Anti-inflammatory effect of tryptophan metabolites in fermented rice bran” was held on the 6th of August. On the same day, I also attended some presentation and symposium on several topics such as early life toddler physiology-gene expression & food innovation, and approaches to control obesity in Asia. The next day, August 7th was the day for oral presentation. The presentation was titled “Potential benefits of fermented rice bran supplementation on muscle atrophy in streptozotocin-induced diabetic rats”. On top of this, I also attended lectures on the topic of prebiotics for gut microbiota support and beyond. The flight from Denpasar to Jakarta departed on the afternoon of 7th August. Since it was the beginning of a new term in the university, I attended some discussion session and attended some meetings in Bogor Agricultural University starting from the 12th of August. The discussed topics revolted around the approach and result of the fermented rice bran research that has been done in Bogor Agricultural University and in Tohoku University. We also deliberated recent research topics in the field of nutrition, functional food and ingredients, and food technology. These discussion sessions happened sporadically until Friday, 23rd of August. The flight back from Jakarta to Tokyo departed on the 26th of August, and arrived on August 27th.


Throughout this chain of programs, I managed to gain some connections and insight on the recent development of the research on fermented food, amino acid and functional food in general. I also managed to learn some intervention programs that had been conducted in several areas in Asia, and the trends on functional foods and its popularity among their consumer. There were chances to see the industry point of view and recognizing several functional food products that already in circulation of the general public. Overall, I think this experience will be useful in tackling the questions and problems that might arise in my own research. It will also assists the development of new research topic in the future and ensure that the next research will be valuable to the public health and wellness.


The 10th Conference of Asia-Pacific Association of Chemical Ecologists (APACE 2019)参加報告

 私は貴財団の支援を受けて、2019年10月8日~13日にかけて中国、杭州で開催されたThe 10th Conference of Asia-Pacific Association of Chemical Ecologists (APACE 2019)に参加し、ポスター発表を行いました。APACEは環太平洋地域の化学生態学を専門とする研究者を対象とした国際学会で、1997年に第1回大会が開催されてから今回で10回目の開催となります。今回の学会中には169題の口頭発表と66題のポスター発表があり、各国から300人を超える研究者が集まりました。
 ポスター発表では、キャベツ栽培における葉ダイコンリビングマルチを利用した害虫の抑制効果について報告を行いました。現在の作物栽培では化学農薬に偏重した病害虫防除体系を改め、適切な防除技術を矛盾なく組み合わせる総合的病害虫管理(IPM)に基づいた防除体系を構築することが望まれています。私が発表した葉ダイコンリビングマルチは、化学農薬に頼らない新たな害虫防除技術としてIPMに与する研究となります。本会は近年になってIPMに力を入れている中国での開催ということで、私と同じように新たな防除技術を試験している研究者が多数参加していました。したがって発表内ではそういった研究者の方々と専門性の高い議論を交わすことができたうえ、鋭い質問や貴重な意見をもらうことができました。英語での発表ということで、こちらが聞き取れなかったり、言葉に詰まったりすることもしばしばありました。それでも粘り強く説明を続けた結果として、たくさんの方から興味深い研究だと評価してもらうことができました。努力の甲斐あって、学会の最後にはBest Student Poster Presentation Awardを受賞することができました。流暢に英語を喋ることができなくても、発表への姿勢や研究内容をしっかりと評価してもらえたのだと万感の思いでした。

氏名:加藤 萌子

 私は、2019 年11 月4 日から6 日に台湾、台北にて開催された、AMBS 2019 (4 th Asian Marine Biology Symposium) に参加しました。私は、この学会において、ポスター発表を行いました。
開催地の台北市は、台湾北部に位置する台湾の主要都市です。今回、私は初めての海外渡航であり、異国の空気を体感できることに心躍らせていました。台北は亜熱帯気候であり、11 月の肌寒くなってきた日本とは異なり、非常に過ごしやすい気候でした。道端に植えられている木、マンゴーやドラゴンフルーツを販売するお店からも、植生の違いが感じられました。街を散策すると、漢字ばかりの看板、多数の路上販売店が目に入り、日本と違った街並みを楽しむことができました。このように、初めての異国情緒を感じる一方で、台北には日本からの観光客も多く、商店街では、観光客の日本語と店員さんの日本語が飛び交っていたり、日本のコンビニエンスストアが多く散見されたりとなんとも不思議な感覚でした。学会のパーティーや、留学生の友人に紹介してもらったお店での中華料理は日本と違う独特な風味が感じられ、量がとても多い上、どれもとても美味しいく、異国の食文化を楽しむことができました。
AMBS は、2 年ごとにアジアの各都市で開催されており、今回で4 度目の開催でした。台湾、日本、タイ、韓国といったアジア諸国から約 200 名が参加しました。AMBS はアジアの海洋生物の研究者の研究交流を目的としており、研究対象となる生物、海域、分野 (生態学、生理学、分類学等) が異なる研究者が一堂に会します。3 日間を通して、幅広い研究領域の発表、セッションを聞き、海洋生物・環境についてより考えを深めることができました。加えて、内容が面白い研究や、伝え方の上手なプレゼンテーション、同世代の研究者の活躍を見て、自分ももっと頑張らなくてはと刺激を受けました。また、学会全体として、アットホームで和気あいあいとした雰囲気を感じました。休憩やポスターセッション中には、おいしいお菓子をいただきつつ、パーティーやバンケットでは美味しい中華料理と現地の伝統的な歌と楽器の演奏を聴きながら、研究者の方々と交流することができました。話す内容は、アイデア交換や共同の実験計画など研究に関することだけでなく、台湾での観光や趣味についてなど多岐に及びました。私自身も、研究に関する情報を提供していただく約束を取り付けたり、他大学の学生とお互いの研究室の風習について話したりと楽しく交流しました。
私は、Seasonal change of benthic diatoms in Gamo Lagoon, Miyagi Prefecture, northeastern Japan というタイトルでポスター発表を行いました。底生珪藻は干潟域の重要な一次生産者で、生物生産の基礎を担う生物です。しかし、その研究の煩雑さから研究例が少なくなっています。今回、その底生珪藻の個体数密度、群集組成を長期間にわたって分析したデータを発表しました。自分の発表した研究には未解明な部分、課題も多いので、他の研究者から、生物の採集方法やデータ解析方法、海洋の一般的な知識など様々な面からのアドバイスを頂きました。私は、学会発表は初めてであり、その上英語での発表であったため、数カ月前から英語の勉強をし、発表練習も何十回と繰り返して臨みました。そのため、本番では、拙い英語ではありますが、落ち着いて発表、意見交換をすることができました。


14th International Conference of the East and Southeast Asia Federation of Soil Science Societies
(ESAFS 2019)参加報告

氏名:大沼 佐保子

 私は11月2日から8日にかけて開催された、14th International Conference of the East and Southeast Asia Federation of Soil Science Societies (ESAFS 2019)に参加し、口頭発表を行いました。
ESAFSは東・東南アジア地域における土壌科学、肥料管理、植物栄養学の研究者たちのプラットフォームの役割を果たしている学会であり、今回は国立台湾大学のGIS Convention Centerにおいて、「持続可能な農業のためのスマート土壌管理」をメインテーマに講演や口頭発表、ポスター発表が行われました。
また、学会中には他の研究者の方々の口頭発表・ポスター発表の他、著名な研究者の方々による講演も実施されました。講演は、気候変動による影響が特に深刻であると予想される台湾において進められている、「Smart Agriculture 4.0」と呼ばれる、持続可能な農業を実現するための土壌情報を含むブロックチェーン技術を用いた農業のIT化プロジェクトの紹介の他、「気候変動」・「持続可能な農業」をキーワードに行われました。それらを通し、日頃自分の研究テーマに没頭する中で薄れていた、農学を研究するうえでの現在や未来の環境問題や食糧問題解決への貢献という大きなテーマを改めて強く認識させられました。
