我が国においては、1996年から「豚コレラ清浄化5カ年計画」が本格的に開始された。この計画は、まず豚コレラGP生ワクチンの徹底接種することにより群免疫を高めて、野外ウイルスを排除することから始められ、その後にいのししを含めた豚の抗体検査により感染の有無などの実態調査を行いながら、徐々にワクチン接種を中止していくものである。2000年にはワクチン使用が原則中止され、一部都道府県知事の許可に基づき使用されていた同ワクチンの接種も徐々に中止され、2006年4月には全面中止となり、最終的にOIE規約に基づき2007年4月に「豚コレラ清浄国」となった。豚コレラ清浄国へ向けたこのような動きの中で、2004年、我が国屈指の養豚県である鹿児島県において5事例の豚コレラ疑似患畜が確認された。この発生に伴う一連の防疫活動においては、緊急ワクチン接種の強い要請があった中、西欧諸国と同様に、ワクチン接種を行わず、感染豚の摘発と淘汰及び飼養衛生管理基準の遵守により防圧された我が国初のケースとなった。

Cuscuta campestris, a stem parasitic plant, commences its parasitic behavior by forming a specialized disk-like adhesive structure called a holdfast, which facilitates tight adhesion to the stem surface of the host plant. The morphology of epidermal cells in the holdfast is similar to that of the leaf trichome and root hairs of dicotyledonous plants. However, the regulatory network underlying the development of the holdfast has not been elucidated to date. In this study, we assessed the roles of epidermal cell-patterning genes in the development of a holdfast. Epidermal cell-patterning genes of C. campestris, including CcWER, CcGL3, CcTTG1, CcGL2, and CcJKD, were expressed slightly before the initiation of the outgrowth of stem epidermal cells. CcJKD-silencing repressed CcJKD, CcWER, CcGL3, CcTTG1, CcGL2; therefore, CcJKD is an upstream regulator of other epidermal cell-patterning genes. Unlike other genes, CcCPC was not upregulated after attachment to the host, and was not repressed by CcJKD-silencing. Protein interaction assays demonstrated that CcJKD interacted with CcTTG1 and CcCPC. Furthermore, CcJKD-silencing repressed the outgrowth of holdfast epidermal cells. Therefore, C. campestris invokes epidermal cell-patterning genes for the outgrowth of holdfast epidermal cells, and their regulatory mechanism is different from those for leaf trichome or root hairs.

Siは太陽光発電市場の90%以上を占めている代表的な太陽電池材料である.1、2世代型太陽電池研究を主導したSi太陽電池はSi量子ドットをもとにして、次世代型太陽電池への可能性を示している。Siの量子特性は以前研究から証明されたにもかかわらず、多重励起子生成の実現と太陽電池への応用は相変わらず非常に難しい課題である.本研究では,Si量子ドットとポリマーを用いて有・無機ハイブリッド太陽電池を研究した.ポリマーの割合調節を通じてエネルギーバンドをコントロールして、Si量子ドットのバンドギャップに合わせたバンド構造から電荷の抽出が改善された高効率有・無機ハイブリッド太陽電池を作製した。

<p>In order to surpass the theoretical Shockley-Queisser limit of energy conversion efficiency of single-junction solar cells as well as to lower the cost, advanced concepts and new materials are emerging. By placing a dense array of quantum dots in the active region of a <i>pin</i> solar cell, which consequently leads to formation of a superlattice miniband or intermediate-band, the solar cell efficiency could reach 63% under full sunlight concentration. Recent status and future research opportunities are reviewed.</p>

本稿は昭和四二年七月、文京区立鷗外記念本郷図書館において研究発表をした「鷗外をめぐる人々―平野万里について―」と題する内容に大幅の加筆を施したものである。すなわち同発表が平野万里の略伝の紹介にとどまったのに対し、本稿は特に森鷗外と平野万里との交渉に焦点を当てて、その問題点を追究してみようと試みるものである。本論に入る前に、平野万里の人となりを俯瞰する意味で、まず同人の簡単な年譜を紹介しておきたい。平野万里略年譜○明治一八年(一八八五) 五月二五日、埼玉県北足達郡大門村に甚三の次男として生まれた。本名、久保(ひさやす)。 ○明治二三年(一八九〇)六歳 一家上京して本郷森川町三二番地に住み、煙草小売店を営む。本郷区立駒本尋常高等小学校に入学。

Incision-patterned pottery was excavated at many archaeological sites from the Okhotsk culture dated 300 to 1300 A.D. They are similar to incision-patterned pottery excavated at numerous archaeological sites from the Tokarev culture dated 700 B.C. to 200 A.D. and the Ancient Koryak culture dated 500 to 1700 A.D., on the northern coastal area facing the Sea of Okhotsk. Such resemblances of incision-patterned potteries indicate that these ancient inhabitant groups of Sakhalin and the northern coastal area of the Sea of Okhotsk had some form of contact with each other. Susuya-type pottery peculiar to Sakhalin contains comb patterns. Pottery with comb-patterned ornamentation was excavated at not only Tokarev culture archaeological sites but also at archaeological sites of the Early Iron Age in the northwestern coastal area. In Sakhalin, however, details of the culture with comb-patterned pottery remain unknown. Recent publications reveal that comb-patterned pottery has been excavated at many archaeological sites in Northern Sakhalin and that such pottery belonged to the Nabil’ culture dated 800 to 300 B.C. and to the Pil’tun culture dated 1000 to 400 B.C., both of the Early Iron Age (cf. Fig. 2). These finds clarified the fact that the comb-patterned pottery were from the Nabil’ and Pil’tun cultures in Northern Sakhalin (Fig. 3: 1, 15). Moreover, it is estimated that the comb-patterned pottery of the Susuya-type pottery (Fig. 3: 18, 19 and Fig. 5) appeared in Southern Sakhalin through the influence of Nabil’ culture. At the Kukhtuj VII archaeological site of the Early Iron Age on the northwestern seacoast of the Okhotsk, comb-patterned pottery similar to those characteristic of the Nabil’ and Pil’tun cultures was excavated (Fig. 7: 1, 8, and 9). The age of the Kukhtuj VII site is estimated to be from 600 to 500 B.C. Comb-patterned pottery was also excavated at the Ujka site of the Early Iron Age on the northern seacoast of the Okhotsk (Fig. 8: 1, 2, 13, 14, 16, 19?26, 30?32). The age of the Ujka site is estimated to be from 1 to 500 A.D. At the Spafar’ev archaeological site of the Tokarev culture dated 700 BC to 200 A.D. on the northern seacoast of the Okhotsk, comb-patterned pottery similar to those characteristic of the Nabil’ and Pil’tun cultures was excavated (Fig. 10: 2?8). The age of the Spafar’ev site is estimated to be between 300 B.C. and 100 A.D. The comb-patterned potteries excavated at the Ujka and Kukhtyi VII sites on the northwestern coast of the Sea of Okhotsk and the Spafar’ev site on the northern coast of the Sea of Okhotsk resemble the comb-patterned pottery excavated at many sites of the Nabil’ and the Pil’tun cultures. The ages of these sites are not coincidental, being within the range of the Tokarev culture period dated 700 B.C. to 100 A.D. Therefore, it is supposed that these comb-patterned potteries at the Ujka, Kukhtuj VII, and Spafar’ev sites appeared by means of contact and mingling of inhabitants in North Sakhalin, on the northwestern and northern seacoasts of the Okhotsk. A route for traffic was most likely opened by means of contact by peoples of the Nabil’ and the Pil’tun cultures in Northern Sakhalin, by peoples of the Early Iron Age on the northwestern seacoast of the Okhotsk, and by those of the Tokarev culture on the northern seacoast of the Okhotsk; hence, this trading route provided a way for the comb-patterned pottery to be spread from Northern Sakhalin to the northwestern and northern seacoasts of the Okhotsk.

In vitro acclimatization has been validated as the successful key to harden the plantlets before transplanting to ex vitro conditions. In the present study, we investigated the potential of different sugar types (glucose, fructose, galactose, sucrose) in regulating morphological, physiological and biochemical strategies, survival percentage and growth performance, and rhizome traits of turmeric under iso-osmotic potential. Leaf greenness (SPAD value) in acclimatized plantlets (4% glucose; −1.355 MPa osmotic potential) of ‘ST018’ was retained and greater than in ‘PB009’ by 1.69-fold, leading to maintain high Fv/Fm (maximum quantum yield of PSII), ΦPSII (photon yield of PSII) and Pn (net photosynthetic rate) levels, and retained shoot height, leaf length, leaf width, shoot fresh weight and shoot dry weight after one month upon transplanting to ex vitro conditions. In addition, Pn, Ci (intracellular CO2), gs (stomatal conductance) and E (transpiration rate) in acclimatized plantlets (6% sucrose; −1.355 MPa osmotic potential) of ‘PB009’ were stabilized as physiological adapted strategies, regulating the shoot and root growth and fresh and dry weights of mini-rhizome. Interestingly, the accumulation of total curcuminoids in mini-rhizome derived from 6% sucrose acclimatized plantlets of ‘ST018’ was greater than in ‘PB009’ by 3.76-fold. The study concludes that in vitro acclimation of turmeric ‘PB009’ and ‘ST018’ using 6% sucrose and 4% glucose, respectively, promoted percent survival, physiological adaptations, and overall growth performances under greenhouse conditions.
