ミラベグロン(ベタニス®錠)は選択的β3アドレナリン受容体作動薬であり,現在,新規過活動膀胱治療薬として本邦で使用されている.ヒトβアドレナリン受容体発現細胞を用いた機能実験において,ミラベグロンはヒトの膀胱弛緩に主に関与しているβ3アドレナリン受容体に選択的な刺激作用を示すことが確認された.ラットおよびヒト摘出膀胱標本を用いた機能実験において,ミラベグロンはカルバコール刺激による持続性収縮に対して弛緩作用を示した.麻酔ラットにおいて,ミラベグロンは静止時膀胱内圧を低下させたが,ムスカリン受容体拮抗薬であるトルテロジンおよびオキシブチニンは明らかな低下作用を示さなかった.また,麻酔ラットにおいてミラベグロンは,律動性膀胱収縮の収縮力に影響を及ぼさなかったが,オキシブチニンは収縮力の低下を引き起こした.ミラベグロンは過活動膀胱モデルラットにおいて,減少した平均1回排尿量を増加させた.尿道部分閉塞ラットにおいて,ミラベグロンは排尿圧および残尿量に影響を及ぼすことなく排尿前膀胱収縮回数を減少させたが,トルテロジンおよびオキシブチニンは,高用量投与時にそれぞれ1回排尿量減少および残尿量増加作用を示した.以上の非臨床薬理試験により,ミラベグロンはムスカリン受容体拮抗薬と異なり,排尿時の膀胱収縮力を抑制することなく1回排尿量を増加させることが明らかとなった.過活動膀胱患者を対象とした米国および欧州第III相臨床試験において,ミラベグロンは過活動膀胱の諸症状に対して優れた有効性および忍容性を示した.口内乾燥の発現率は,ミラベグロン群とプラセボ群で同程度あり,トルテロジンSR群より低かった.以上,非臨床薬理試験および臨床試験の結果から,ミラベグロンは既存薬とは異なる新たな作用機序により,ムスカリン受容体拮抗薬に特徴的な口内乾燥の発現率を低減し,過活動膀胱の諸症状に対して改善効果を示す薬剤であることが示された.

The paper empirically examines the contribution of forest-environmental income, and its role in well-being outcomes among the forest dependent households in rural Nepal. The results are based on a one-year survey of 303 households that included the detailed information on household demographics, income and assets and the people's perception in the change in their well-being compared to the last five year. To capture likely non-linear dynamics of well-being status, a probit regression model is tested. Overall, forest environmental income contributed an average of 16% of the total household income. Relative environmental reliance decreased with rising income while absolute environmental income increased. The perception of well-being was related to shock exposure and households' endowments to cope with shocks. In particular, households exposed to several consecutive shocks (two or more severe shocks) over the course of five years significantly reported to be worse-off. The limited role of forest in improving the well-beings of the households is associated with their limited access to the resources. Identification of income groups, their expected wealth status, and asset and access constraints that limit economic advance are used to suggest appropriate targets of intervention.

A 9.0 magnitude (M) earthquake with an epicenter off the Sanriku coast occurred at 14: 46 on March 11, 2011. TEPCO Fukushima Daiichi Nuclear Power Plant (F-1 NPP) was struck by the earthquake and its resulting tsunami. Consequently a critical nuclear disaster developed, as a large quantity of radioactive materials was released due to a hydrogen blast. On March 16th, 2011, radioiodine and radioactive cesium were detected at levels of 177 Bq/kg and 58 Bq/kg, respectively, in tap water in Fukushima city (about 62km northwest of TEPCO F-1 NPP). On March 20th, radioiodine was detected in tap water at a level of 965 Bq/kg, which is over the value-index of restrictions on food and drink intake (radioiodine 300 Bq/kg (infant intake 100 Bq/kg)) designated by the Nuclear Safety Commission. Therefore, intake restriction measures were taken regarding drinking water. After that, although the all intake restrictions were lifted, in order to confirm the safety of tap water, an inspection system was established to monitor all tap water in the prefecture. This system has confirmed that there has been no detection of radioiodine or radioactive cesium in tap water in the prefecture since May 5th, 2011. Furthermore, radioactive strontium (89 Sr, 90Sr) and plutonium (238Pu, 239Pu+240Pu) in tap water and the raw water supply were measured. As a result, 89 Sr, 238Pu, 239Pu+240Pu were undetectable and although 90Sr was detected, its committed effective dose of 0.00017 mSv was much lower than the yearly 0.1 mSv of the World Health Organization guidelines for drinking water quality. In addition, the results did not show any deviations from past inspection results.

The hand is one of the important qualities of bath towels. It is interesting to study what physical properties of bath towels correlate to their hand. In this paper, the relationship between the sensory values for the good feel and physical properties of twelve bath towels was studied by means of the principle regression analysis and the correlation analysis. The results are as follows.(1) As a result of principal component analysis, it was found that two principal component “good in touch” and “sturdy and drying property” were chosen to represent the hand of bath towel.(2) The compression feeling was affected by compression properties((To-TM), compression ratio, compression energy, and recovery energy). And the softness feeling was affected by the friction property(MMD), and the warmth by the thermal property(q-max).

The purpose of this study is to clarify the sensitive elements which affects sustainability of NPO Corporation management. We analyzed the data of hearing survey using the text-mining methods, extracted the main elements about “troubles in operation,” “actions for solution,” and “achievements,” and searched for the relevance between the sustainability and the elements. We found that, In addition to the economic challenges, the efforts of training staffs, the scheme of raising name values, and the achievement in improving motivation also have influence on the sustainable development. And we finally got a conclusion that when facing difficulties in management, identifying the problem clearly and trying various measures leads to the improvement of staff motivation. And this process was also the characteristic of sustainable development of NPO Corporation.

In this study, we investigated how the temporal envelopes contribute to the recognition of isolated syllables, words, and sentences in noise-vocoded speech, under comparison with the influence of spectral resolution. The spectral and temporal resolutions of speech materials were systematically manipulated by a noise-vocoding technique. Japanese monomoraic syllables, meaningful and meaningless words, and sentences were used as test speech materials. The original speech sound was spectrally separated by a filter bank, and each spectral band was replaced with band noise, preserving its original temporal envelope. Spectral resolution was controlled by varying the number of spectral bands as 4, 8, or 16 bands. Temporal resolution was altered by smoothing the amplitude envelope using a low-pass filter with cut-off frequencies at 4, 8, or 16 Hz. Results demonstrated an increased dependence on temporal resolution in comparison with spectral resolution for the recognition of speech materials at higher structural levels (i.e., monosyllables, words, and sentences). This increased temporal dependence suggests that the temporal envelope in noise-vocoded sentences contained a greater amount of suprasegmental information, such as coarticulations, prosodies, and rhythms, in the original speech sound.

We herein report the case of an 84-year-old man with steroid-dependent adult-onset Still's disease (AOSD) whose daily steroid dose was successfully tapered after etanercept treatment. The corticosteroids worked well initially, and the patient went into remission promptly; however, he suffered a relapse due to steroid tapering. Because treatment with cyclosporine and methotrexate was ineffective, reducing the steroid dose was difficult, and the corticosteroids induced myopathy and diabetes. However, steroid tapering was accomplished in combination with etanercept therapy, and the patient's steroid-induced side effects disappeared. Etanercept should therefore be considered as a steroid-sparing treatment option in patients with steroid-responsive, steroid-dependent AOSD.

Dissolved nitrogen concentration of bulk precipitation and stream water were investigated on the Kabura river watershed (Western part of Gunma Pref.) and the Oze-numa lake. Also dissolved nitrogen concentration of stream (upper end of each river) around the Echigo Mountains including Fukushima, Niigata and Gunma Pref. were analyzed. NOx-N concentration showed most high value on the Kabura river watershed, and rather high value on the Tone river. In Niigata Prefectural side of Echigo Mountains, nitrogen concentration of the stream water lowered in 1/2 and in Fukushima side of that nitrogen concentration decreased to 1/5 level.Rather high concentration of inorganic nitrogen on the upper stream of Tone River is thought to be derived from the air contaminants which comes flying from the metropolitan area with the sea wind in summer.

1.はじめに 東アジア地域では測器による気象観測が最近100年間程度に限られるため,100年以上の気象観測データにもとづく気候変動の解析が困難であった.近年,地球規模の気温上昇が懸念される中,人間活動の影響が小さい時期の気象観測記録を整備し,長期的な気候変動を検証することは,正確な将来予測につながると考えられる.またこれまで数多く行われてきた古日記の天候記録による気温の推定値を検証する際にも,古い気象観測データが有効であると考えられる. Zaiki et al.(2006,2008)は1880年代以前の日本(東京・横浜・大阪・神戸・長崎),また中国(北京)における気象観測記録を均質化し,データを公開している.本研究はこれまで整備してきた19世紀の気象観測記録とほぼ同時期の1852~1868年に,水戸で観測された気温の観測記録を均質化し,現代のデータと比較可能なデータベースを作成することを目的とした.さらにそのデータを使用して,小氷期末期にどのような気温の変化があったかを検討する. 2.資料・データ 19世紀の水戸における気温観測記録は,水戸藩の商人であった大高氏の日記(大高氏記録)に含まれている.原本は東京大学史料編纂所に,写本が茨城大に所蔵されている.寒暖計による気温観測は1852~1868年にわたり,1日1回朝五つ時に実施されている. 水戸気象台の月平均値は要素別月別累年値データ(SMP:1897年~),日・時別値は地上気象観測日別編集データ(SDP:1991年~)を使用した. 3.均質化 大高氏記録の気温は,華氏(°F)で観測されているため,摂氏(°C)へ換算した.さらに,当時の観測時刻である不定時法の「朝五つ時」は季節によって変動するため(午前6時半~8時頃),各月の平均時刻を算出した.そして,水戸気象台の気温時別データを利用して,各月の朝五つ時のみの観測値から求めた月平均気温と24時間観測による月平均値を比較し,均質化のための値を算出した.均質化後には,最近50年間の観測データとの比較によって異常値を判別し,データのクオリティチェックを行った. 4.19世紀の水戸における気温の変動 今回,大高氏記録から所在が判明した1852~1868年の水戸の気温データは未だに断片的ではあるが,1850・1860年代は寒暖差が大きく,夏(8月)は水戸の平年値よりも0.9°C高く,冬(1月)は0.5°C寒冷であったことが明らかとなった.これは,すでにデータベース化している19世紀の東京・横浜での気温の変動とほぼ一致する傾向にある.今後は,大高氏による観測環境がどの程度直射日光の影響を受けやすかったのか等,検討する必要がある.

Solid oxide electrolysis cell for electrolysis of CO2 to CO was studied with the cell using LaGaO3-based electrolyte at the intermediate temperature (i.e. 973–1173 K). Various metal additives to Ni were examined for cathode to CO2 reduction and it was fund that Ni added with Fe shows high activity and the current density of 1.5 A/cm2 was achieved at 1.6 V and 1073 K on Ni–Fe (9:1) cathode. Improved electrolysis activity was explained by the expanded reaction site which may be assigned the fine particle of Ni. Furthermore, effects of additives to Ni cathode were studied and it was found that the electrolysis current could be much improved by addition of Fe to Ni. Effects of oxide ion conductor mixing with Ni–Fe were further studied and it was found that mixing La0.6Sr0.4Fe0.9Mn0.1O3 with Ni–Fe bimetal is the most effective for achieving high electrolysis current of CO2 of 2.07 A/cm2 at 1.6 V and 1073 K.

The temperature-sensitive triblock copolymer poly-(D, L-lactic acid-co-glycolic acid) (PLGA)-polyethylene glycol (PEG)-PLGA (PLGA-PEG-PLGA) is an FDA-approved material that has the ability to provide a sustained release of drugs and/or proteins. Platelet-rich fibrin(PRF)is second generation platelet concentration that contains growth factors such as transforming growth factor-β1 (TGF-β1), platelet derived growth factor-AB (PDGF-AB), and insulin-like growth factor-I (IGF-I). These growth factors affect the migration and proliferation of diverse cell types, including endothelial cells, smooth muscle cells, and osteoblast-like cells. This study sought to combine the hydrogel into scaffolds in order to serve as a sustained release system for PRF-derived growth factors. Poly (lactic-co-glycolic) acid (PLGA) and nano-hydroxyapatite (nHA) were used to prepare the hydrogel-containing scaffolds with the PRF-derived growth factors. We then investigated the effects of the hydrogel on modulating the activity of osteoblasts in vitro. We indicated that the hydrogel (Gel) was well-distributed in the inner surface of scaffolds, which themselves exhibited relatively interconnected pores with uniform sizes. The addition of the hydrogel didn’t affect their inherently high porosity. In vitro release tests indicated that the system containing nHA/PLGA/Gel/PRF provided for a slow and sustained release of PRF-derived growth factors. The results from our in vitro studies indicated that the MG63 cells cultured with both scaffold media extracts did not appear to have cytotoxic responses, and the nHA/PLGA/Gel/PRF system could improve the adhesion and proliferation of MG63 cells when compared to controls (p < 0.05). This in vitro evaluation suggests that the hydrogel-scaffold system is suitable as a model for bone tissue engineering, and that it allows for the sustained release of growth factors to improve bone reconstruction.
