スケート選手を対象とし,寒冷環境下での身体活動がサイトカイン応答に及ぼす影響を寒冷適応の有無から検討した.寒冷環境適応者のショートトラックスケーター,寒冷環境不適応者のインラインスケーター,それぞれ男子 10 名を被験者とし,60 分間の寒冷 (5~8℃) または常温 (20~25℃) にて安静状態を維持した後,最大酸素摂取量の 65%強度に相当する自転車エルゴメーター運動を 60 分間負荷し,常温で 120 分間安静状態維持を実施した.採血は,安静時,寒冷ないし常温下で 60 分安静後,運動負荷直後,30 分後,60 分後,120 分後の計 6 回肘静脈より行い,血漿を分離した.サイトカインの濃度は酵素免疫測定法により測定した.寒冷環境適応者が常温で運動すると IL-1ra,IL-10, IL-12p40 などのサイトカインが誘導されるが,これらの運動時のサイトカイン応答は寒冷(冷却)によって抑制できることが評価できた.<br>

Constituents of the Japanese sea hare Dolabella auricularia collected in Mie Prefecture, Japan were examined by using bioassay, and new cytotoxic depsipeptides, dolastatins G (1) and H (14) and isodolastatin H (15) were isolated. Dolastatin G (1) showed cytotoxicity against HeLa-S_3 cells with an IC_<50> of 1.0μg/mL. On the basis of 2D NMR technique, dolastatin G (1) has proved to be a 35-membered cyclic depsipeptide which consists of a hexapeptide and two new hydroxy acids. The absolute stereochemistry of the hexapeptide moiety was determined by the chiral HPLC analysis of amino acids obtained by acidic hydrolysis of dolastatin G (1). The absolute stereochemistry of two hydroxy acid parts was determined by the enantioselective synthesis of two corresponding fragments obtained by degradation of dolastatin G (1). For the purpose of confirming the stereostructure of dolastatin G (1), synthetic studies on dolastatin G (1) have been carried out. Three subunits, 7, 10, and 11, were synthesized, coupling of which gave seco acid 13. The synthesis of dolastatin G (1) from seco acid 13 is in progress. A 1:1 mixture of dolastatin H (14) and isodolastatin H (15) showed potent cytotoxicity against HeLa-S_3 cells with an IC_<50> of 0.00381μg/mL. On the basis of spectroscopic data, dolastatin H (14) has proved to be a linear tetrapeptide which contains two unusual amino acids and is esterified at the C-terminus by the primary hydroxyl group of 3-phenyl-1,2-propanediol. Isodolastatin H (15) is the structural isomer of dolasatin H (15), in which the tetrapeptide is esterified at the C-terminus by the secondary hydroxyl group of 3-phenyl-1,2-propanediol. The absolute stereochemistry of dolastatin H (14) and isodolastatin H (15) was unambiguously determined by the enantioselective total synthesis.

It is difficult to say why using household eco-account books, which are said to be very effective in reducing environmental impact, is not popular today. We believe that the reason for this lies in not only the design of the books, but also the attitude of the people who use them. In order to clarify this, we analyzed the background, the attitude, and the description of the books of twenty-one people who had been using the books for more than three years. The research showed that those who had been keeping these books were generally more than sixty years old and had a lot of free time. It also showed that they could be classified into four different groups. We named them as follows: “Nonbiri” are the members who use the books casually. “Kotsukotsu” use the books on a regular basis. “Waiwai” tend to work in groups, and “Takumi” thoroughly investigate the cause and are active in environmental investment. Of these groups, the people identified as members of Waiwai and Takumi had been using the books relatively longer than the other groups, and their books showed the effect of the reduction of emissions of carbon dioxide. As a result of our research, we came to the following conclusions: (1) It is important to understand that there are two stages, reducing energy on a day to day basis and reducing CO2 by environmental investment. (2) Book-keepers who would like to be part of “Takumi” should be identified. (3)Creating groups like “Waiwai“ should be encouraged.

これまで超音波の骨に対する作用を解析した研究は、骨芽細胞の株細胞を用いたin vitro の研究が主流であり、骨芽細胞と破骨細胞の相互作用を解析する良いモデルがない。また歯の形成に対する作用においても、in vivo の系が主流であり、in vitro の良いモデル系が求められている。その機構を解析する硬組織モデルとして魚類のウロコとマウスの歯胚を用いて、低出力超音波パルスの影響を解析した。その結果、ウロコを用いて低出力超音波パルスの最適な条件を見出した。その条件では、歯胚の特に象牙質の形成に効果があり、ウロコを用いたGeneChip 解析により超音波に対する破骨細胞のシグナル伝達経路を初めて明らかにすることができた。さらに新規化合物の骨に対する作用も解析して、骨疾患の治療に有望な化合物を見出した。

似顔絵生成問題は、顔の物理的表現から個人性特徴の知覚的記述・表現を抽出し、これを改めて物理的に生成する問題として捉えることができる。筆者らは、これをコンピュータによる実現する一つの試みとして、顔の物理的な個人性特徴を抽出するための「平均顔」と、その特徴の知覚的記述を獲得するための「中割り法」によるズレの誇張法、などを基本原理とした似顔絵師システムPICASSOを開発してきた。これまでのPICASSOでは、主に、二次元的な扱いで上述の特徴抽出と誇張メカニズムを実現してきた。本論文では、これを三次元に拡張し、三次元立体表示による「似顔絵レリーフ」をはじめとした簡易な三次元似顔絵生成を実現するための一手法について提案する。

In this research, walking trail is analyzed from “sense of walking” paying attention to “the change nature of walking trail.” Analysis is precedence research in a soundscape. It carried out to reference from the viewpoint of a “sound”, a “phrase”, “harmony”, and a “melody.” This is because it is necessary to take in time progress about the correlation and analysis result of the composition element of “walking trail” seen from “sense of walking” to regard as a sequence. As a result of analysis, the acquired knowledge is summarized to below. (1) as the “harmony” of walking trail, eight types; “Circuit type”, “Relax type”, “Straight-flat type”, “Approach type”, “Well-textured straight-flat type”, “Acrobatic type”, “Up and down type”, and “Particular type” were extracted (2) consequently, high “harmony” of the rate for which it accounts on a “course”—“Circuit type” and “Relax type” (3) The type of six “melodies” was extracted as changes of “harmony.” (4) It became clear to correspond with the impression acquired by the feature of the type of the “harmony” obtained from “a sense of walking” actually walking that. When improving walk space, it can be said that the space which can obtain many feelings not only from vision but from body nature including “walk feeling” is very rich space.
