In the J League, the number of clubs having a small business scale is increasing with the age of the league, resulting in a disparity in business scale. There is a certain correlation between the business scale and ranking. In professional sports, the ratio of personnel costs for players to the total cost is large, and the performance (rank) is determined by the ability of the players possessed by the club. It is arguable that the business scale is explained by the management ability of the club (organizational ability) or the ability of the management, and it is also explained in part by the change in rank. V-Varen Nagasaki was pushed to the point of management failure in 2017. Then the founder of a major mail order business took over the management of the tea, which was ranked second in J2, and decided that it would be promoted to J1 in the next year. In this study, we interviewed the president, directors, and captains. V-Varen Nagasaki's management philosophy is Action, Passion and Mission ; having the meaning of thoroughly improving the environment, building relationships of trust with players, and establishing and implementing basic policies. V-Varen Nagasaki overcame the management crisis because of the management of professional managers and the convenience model in J League, which is a business model for controlling and instructing clubs. This study shows that it is important for professional sports clubs, which are public entities, to have a proven professional manager participate in the management of the J club.

This study was performed to investigate the occurrence of selected insecticides (seven neonicotinoid insecticides and their four metabolites and the phenylpyrazole insecticide fipronil) in Hiuchi-Nada (48 samples) and Osaka Bay (4 samples), Seto Inland Sea, Japan, in 2016 and 2017. Among the insecticides examined, dinotefuran was exclusively detected in both the bays. Its concentration (9.45 and 32.4 ng/L in Hiuchi-Nada and Osaka Bay, respectively) and detection frequency (68.8% and 75.0% in Hiuchi-Nada and Osaka Bay, respectively) were the highest in September, which were closely related to its agricultural application. Furthermore, we observed a higher concentration of the insecticide in the surface layer of the water column than in the bottom layer. Considering that the water temperature was constant through the water column in September, insecticides were transported to estuarine areas and were eventually distributed around the surface waters of the bays. Finally, we inferred that the ecological risks posed by dinotefuran in the bay areas were expected to be too low to cause adverse effects on the resident estuarine and marine crustaceans examined.

At DNA replication forks, the overall growth of the antiparallel two daughter DNA chains appears to occur 5′-to-3′ direction in the leading-strand and 3′-to-5′ direction in the lagging-strand using enzyme system only able to elongate 5′-to-3′ direction, and I describe in this review how we have analyzed and proved the lagging strand multistep synthesis reactions, called Discontinuous Replication Mechanism, which involve short RNA primer synthesis, primer-dependent short DNA chains (Okazaki fragments) synthesis, primer removal from the Okazaki fragments and gap filling between Okazaki fragments by RNase H and DNA polymerase I, and long lagging strand formation by joining between Okazaki fragments with DNA ligase.

【症例】14歳, 女性【主訴】左示指刺創【現病歴】家庭科の授業中にミシンを用いて裁縫中に誤って左示指の末節にミシン針が刺さり救急要請となった。救急隊はミシンを破壊し本体の一部をつけたまま搬送した。【来院後経過】救急外来にて針に付着した布押さえの部分を工事用ペンチで破壊した。針と糸が共に指を手背側から手掌側へ貫通している状態であった。左示指に局所麻酔し, 針の末端部分の一部を切断し, 手掌側の針の先端をペンチで把持して引き抜くように糸と共に除去した。除去後, 止血を確認し, 帰宅とした。【考察】ミシンの縫い目は2本の糸が絡み合うことによって作られる。その構造上ミシン針の糸通しは針の先端についているためミシン作業中の刺創では針と共に糸が必ず体内を通過する。その構造を把握しないで針だけを抜去すると糸が皮膚の中に残存することがある。ミシン針の貫通創の処置では抜去時にミシンの仕組みを知る必要があると考えた。

焦点てんかんは, 焦点の局在により, 発作に対する睡眠の影響という点でそれぞれ異なった特徴がある。後頭葉てんかんは覚醒中の発作が多いのに対して, 前頭葉てんかんは睡眠中の発作が半数以上を占める睡眠てんかんの代表的疾患である。前頭葉てんかんでは, 焦点性間代発作, 非対称性強直発作, 過運動発作 (運動亢進発作) といった運動症状をきたす発作がみられる。睡眠中に異常運動・行動をきたすため, ノンレムパラソムニア (ノンレム睡眠からの覚醒障害群) との鑑別が問題となる場合があるが, 発作が一晩に複数回群発することがある, 運動症状がステレオタイプで無目的である, といった点が鑑別点として重要である。終夜睡眠ポリグラフ中にイベントが記録されれば, 前頭葉てんかんの発作はノンレム睡眠stage N2に起きることが最も多いのに対して, ノンレムパラソムニアはノンレム睡眠stage N3に起きる点が特徴である。

薬物の多くは,血漿中でアルブミンやα1-酸性糖タンパクなどのタンパク質へ結合している.アルブミンは脂溶性の高い酸性化合物,α1-酸性糖タンパクは塩基性化合物に対し高い親和性を示す.タンパクへ結合した薬物は細胞膜を透過することができないため,血漿中の遊離型薬物のみが組織に分布して薬効や毒性を発現し,代謝や排泄を受けて体内から除去される.したがって,血漿中タンパク結合は薬物の体内動態や薬効,毒性に多大な影響を及ぼす.血漿中タンパク結合には種差があり,体内動態や薬効,毒性の種差の原因となる.また,血漿中タンパク結合は病態や薬物間相互作用によっても変動し,薬効の減弱や副作用の増強など臨床上好ましくない現象を引き起こす場合がある.したがって,薬物の血漿中タンパク結合は医薬品の探索・開発を通じて評価しなければならない重要な項目の一つである.

Liparis koreojaponica Tsutsumi, T. Yukawa, N. S. Lee, C. S. Lee & M. Kato var. kiiensis Suetsugu & Tsutsumi (Orchidaceae) from Nara Prefecture, Japan is described as a new variety. It is similar to L. koreojaponica var. koreojaponica, but differs in spacing of the flowers (ca. 1.5 cm apart in the former vs. ca. 2 cm apart in L. koreojaponica var. koreojaponica), length ratio of rachis/inflorescence (1/3–1/2 vs. 1/4–1/3 in L. koreojaponica var. koreojaponica) and length of the labellum (13–15 mm long vs. 9–12 mm long in L. koreojaponica var. koreojaponica).

Prior to the onset of magmatic activity at the Nakadake first crater, Aso Volcano (SW Japan) from July 2019 to June 2020, multiple small eruptions occurred between April and May 2019. The May 3-5 eruption was one of the largest events during the pre-magmatic activity period. An ash-fall deposit from the early stage of that eruption (15 : 00-18 : 00 in JST on May 3) was distributed to the south of the source crater, whereas the ash erupted after 20 : 00 on May 3 was dispersed southwestwards. The May 3 15 : 00-18 : 00 ash was composed mainly of fine particles (<0.25 mm in diameter) and fell as accretionary lapilli (<0.8 mm). In contrast, ash after 20 : 00 on May 3 consisted mainly of 0.5 mm grains but lacked silt and clay content. Based on an isomass map, the total discharged mass of the May 3-5, 2019 eruption was about 700 tons. Although lithic (50 %) and altered glass (30-40 %) grains were dominant in both ash-fall deposits, they also included small amounts of black to pale-brown fresh glass shards (2-4 %) inferred to be juvenile material originating from newly ascending magma. After the May 3-5 event, small ash emissions occurred intermittently until July 2019. The proportions of fresh glass shards included in the May-July 2019 ash-fall deposits gradually increased; ash erupted in early July contained 7 % fresh glass grains. Small-scale magmatic activity began on July 26, 2019, and continued to mid-June 2020. The April to early July 2019 ash emissions at Nakadake first crater are inferred to be precursor phenomenon of the late July 2019 to mid-June 2020 magmatic eruptions. It is very important to clarify temporal variations in the mass and component characteristics of erupted materials for understanding the sequence of events and predicting future eruptive activity.

Nakadake volcano, the current active center of the Aso central cones (Kyushu), is one of the most active volcanoes in Japan. It has been active since ca. 22-21 cal ka, and has formed the old edifice (22-21 cal ka), the young edifice (around 5 cal ka) and the youngest pyroclastic cone (until present). The lava flows from the young edifice spread on the flank of the volcano several times around 5 cal ka. These lavas are supposed to give stratigraphic markers for constructing the eruptive history of Nakadake volcano, but the similarity in chemical composition and lithology hampers distinguishing and correlating them. We have conducted a paleomagnetic study to distinguish and correlate the lavas since the paleomagnetic secular variation (PSV) provides a high-resolution age information. If lava units have a temporal difference of more than 50 years, they could be distinguished by their paleomagnetic directions. The samples were collected from 9 lava flows and 8 agglutinate layers (welded scoria-fall deposits) and were subjected to the paleomagnetic and rock-magnetic measurements. These samples, from visual inspection, appear to be influenced by chemical alteration in the surface of the outcrop by sulfides of volcanic gases. To check a rock-magnetic effect of the chemical alteration of the lavas and agglutinates, thermomagnetic analyses were made on chip samples from the top (surface of rock) and bottom (inside of rock) of the collected paleomagnetic cores. The thermomagnetic analyses indicate that the core top and bottom samples show the same behaviors, in spite of the difference in color, and the carriers of magnetization of each core are titanium rich (titanium content, x, is about 0.6) and poor (x is about 0.1-0.2) titanomagnetites. The natural remanent magnetization of each sample shows a simple, single vector component in alternating field demagnetization experiments, which well defines the primary component. Site mean directions can be categorized into three different direction groups. These data suggest that the eruption producing lava flows and/or agglutinates occurred at three different ages. Furthermore, the paleomagnetic directions of one group is not consistent with the directions of the eruptive ages of Nakadake young edifice assigned from the previous stratigraphic studies. Comparing these directions with the paleomagnetic secular variation curve which has been drawn from basaltic volcanoes in the northwestern part of Aso central cones, the ages of the direction groups can be assigned to around 6.0-4.3 cal ka and 3.5 cal ka, respectively. This result demonstrates that paleomagnetic studies can greatly contribute for establishing the eruptive histories of volcanos.

Meakandake Volcano is a post-caldera active stratovolcano located on the south-eastern rim of Akan Caldera, eastern Hokkaido, Japan. Recent eruptive activity has occurred in 1955-1960, 1988, 1996, 1998, 2006, and 2008 at Ponmachineshiri, which is one of several volcanic bodies that form the stratovolcano. These events indicate that Ponmachineshiri has a high potential for future eruptions. In order to better understand the hazards posed by Meakandake Volcano, this study focused on the modern eruptive activity of Ponmachineshiri during the last 1,000 years. The authors conducted field observations at outcrops in the summit area, excavation surveys on the volcanic flanks, component analysis for pyroclastic deposits, and radiocarbon dating for intercalated soil layers. As a result, at least four layers of pyroclastic fall deposits derived from Ponmachineshiri during the last 1,000 years were recognized, ranging from Volcanic Explosivity Index (VEI) levels of 1 to 2. In chronological order, the major pyroclastic fall deposits consist of Pon-1 (10th to 12th century; VEI 2), Pon-2 (13th to 14th century; VEI 2), Pon-3 (15th to 17th century; VEI 1), and Pon-4 (after AD 1739; VEI 1), with small-scale (VEI<1) phreatic and phreatomagmatic eruption deposits intercalated within Pon-1, Pon-2, and Pon-3 pyroclastic fall deposits. The presence of scoria and minor pumice in the Pon-1, Pon-2, and Pon-3 pyroclastic fall deposits suggests that these eruptions were phreatomagmatic events. On the other hand, the absence of juvenile materials in the Pon-4 pyroclastic fall deposits suggests that the activity was a phreatic eruption. The decreasing proportion of juvenile materials in eruptive deposits over the last 1,000 years is consistent with a reduced magma contribution and indicates that the development of the hydrothermal system is likely to play an important role in future eruption scenarios for Meakandake Volcano.

In vitro maturation (IVM) is an important reproductive technology used to produce embryos in vitro. However, the developmental potential of oocytes sourced for IVM is markedly lower than those matured in vivo. Previously, NAD+-elevating treatments have improved oocyte quality and embryo development in cattle and mice, suggesting that NAD+ is important during oocyte maturation. The aim of this study was to examine the effects of nicotinic acid (NA), nicotinamide (NAM) and nicotinamide mononucleotide (NMN) on oocyte maturation and subsequent embryo development. Porcine oocytes from small antral follicles were matured for 44 h in a defined maturation medium supplemented with NA, NAM and resveratrol or NMN. Mature oocytes were artificially activated and presumptive zygotes cultured for 7 days. Additionally, oocytes were matured without treatment then cultured for 7 days with NMN. Supplementing the IVM medium with NA improved maturation and blastocyst formation while NAM supplementation improved cleavage rates compared with untreated controls. Supplementing the IVM or embryo culture media with NMN had no effect on maturation or embryo development. The results show that supplementing the maturation medium with NA and NAM improved maturation and developmental potential of porcine oocytes.

スズメ目の鳴禽類, オウム目, ハチドリ目に属する鳥は, 音声学習によってさえずり (歌) を発達させ, 種内のコミュニケーションに用いている。鳴禽類の雄の幼鳥は, 成長期に手本となる鳥の歌を聞いて記憶し練習することで歌を完成させる。この練習時には, 自分のさえずる歌が学習目標となる歌の手本にどれだけ近づいたかを常にモニターするために, 聴覚フィードバックが必要であることが明らかにされている。さらに, 成鳥が完成後の歌を維持するためにも, 同じ理由で聴覚フィードバックが必要であることが, 筆者等の研究も含めた近年の報告により明らかになってきた。成鳥での聴覚フィードバックの重要性については, 鳴禽類の種で異なる結果が報告され, いまだに不明な点が多い。そこで本稿では, 筆者等の研究結果を交え, まず行動レベルで聴覚剥奪後の歌の特徴を比較して, 成鳥の歌の維持における聴覚フィードバックの必要性について検討した。次に, 聴覚剥奪によって成鳥の歌が変化する時に起こる脳内の変化を調べ, 聴覚フィードバックによって制御される成鳥の歌維持の脳内機構についても考察した。
