Gタンパク質結合型内向き整流性K+(GIRK)チャネルは,種々の生理的役割を担うイオンチャネルである.例えば,脳においてはGIRK1とGIRK2のヘテロ複合体が存在し,神経細胞の興奮性を制御しており,心房においてはGIRK1とGIRK4のヘテロ複合体が存在し,心拍の調節に寄与している.われわれは,小分子ライブラリーのスクリーニングにより,抗寄生虫薬として知られるIvermectinがGIRKチャネルを活性化すること,さらに,抗ヒスタミン薬として知られるTerfenadineがGIRKチャネルを抑制することを新たに見出した.本研究では,アフリカツメガエル卵母細胞にGタンパク質結合型受容体の共発現なしに種々のGIRKチャネルを発現させ,二電極膜電位固定法により電気生理学的解析を行い,IvermectinがGIRK2サブユニットに活性化作用を示し,TerfenadineがGIRK1サブユニットに抑制作用を示すことを見出した.次に,キメラ分子や点変異体の網羅的解析により作用の構造基盤の同定を試みた.その結果,Ivermectinの活性化作用にはGIRK2のアミノ末端細胞内領域と第1膜貫通部の間に位置するSlide Helix上のIle82が重要であること,また,Terfenadineの抑制作用にはイオン選択性フィルターの背後に位置するPore Helix上のPhe137が重要であることを見出した.さらに,Ivermectinの活性化作用は,Gタンパク質には依存せず,PIP2を要すること,また,Terfenadineの結合とPIP2の結合には競合が見られることが明らかになった.

シミュレーション技術が幅広い産業分野に普及するとともに,その信頼性をいかに確保するかということへの関心が高まっている。ISO9001の導入以来,検証(Verification)と妥当性確認(Validation)が品質管理のキーワードとなったが,シミュレーションのVerification & Validation(V&V)が今脚光を浴びつつある。原子力においては古くから存在し,かつ新しい側面も持つこのテーマについて計算科学技術部会における取り組みを中心に紹介する。

In Japan, more than 200,000 children experience their parents' divorce annually. To help parents and children cope with problems that result from divorce, a psychoeducational program called Families in Transition (FAIT) has been conducted with Japanese families since 2013. The current authors have noted the importance of understanding the differences and similarities between custodial parents (CPs) and non-custodial parents (NCPs). The purpose of the current study was to examine differences and similarities between the experiences of CPs and NCPs. This study also examined how conflicts occur and ways to improve the program. Participants were 17 parents who participated in the FAIT program. Data were collected via semi-structured interviews and analyzed using the KJ method. The main findings were as follows. Both parents felt hurt and unstable after the divorce. CPs felt as if they were the victims of the divorce, and NCPs felt ignored and lonely as a result of the divorce and not being able to see their children. These emotions hampered their ability to relate to the other parent. Both parents also felt that they had not received sufficient support and information during the divorce. As a result of participating in the FAIT program, both parents felt accepted by sharing their experiences and emotions and they also learned the importance of the child's perspective. CPs changed their view towards visitation, and NCPs' emotions changed when they were treated the same as CPs. Results revealed the importance of understanding both parents' point of view and keeping a balance between sharing personal experiences and maintaining the framework of a psychoeducational program.

The purpose of this study was to devise a scale to assess role reversal and to empirically examine the relationship between role reversal and a child's mental health. Role reversal is known as an abusive parent-child relationship in which the child plays the role of a parent and the parent behaves as a child. Findings with regard to role reversal and the theory of “Amae” have been integrated, allowing role reversal to be conceptualized in terms of “Amae.” Drawing on the theory of “Amae,” the current study conceptualized role reversal as including four subordinate concepts; (1) a parent displaying “Amae” to a child, (2) the parent not fulfilling the child's need for “Amae,” (3) the child not displaying “Amae” to the parent, and (4) the child attempting to satisfy the parent's need for “Amae.” Five hundred and fifty-three high school students were surveyed. The Role Reversal Scale―Parent version (hereinafter denoted as RRS-P) and Role Reversal Scale― Child version (hereinafter denoted as RRS-C) were devised based on exploratory factor analysis. The relationship between role reversal and a child's mental health was subsequently verified using correlation coefficients and multiple regression analysis. Results indicated that role reversal tended to cause worse mental health, low self-esteem, a diminished sense of authenticity, and a high psychological stress response. Therefore, the RRS-P and RRS-C displayed construct validity in terms of the relationship between role reversal and a child's mental health. In addition, results suggested that role reversal can be conceptualized from the perspective of “Amae.”

The purpose of this study was to map the process of rebuilding family relationships through rituals after the death of a family member. Participants were ten Buddhist priests. Data were collected using semi-structured interviews and analyzed using modified grounded theory. Findings resulted in a model with five stages: “attitudes toward the ritual,” “grappling with bereavement,” “the Buddhist priest’s approach,” “rebuilding,” and “collapsing.” These stages were further subdivided into 47 concepts. The main findings were as follows. First, family members have either a positive or negative attitude toward rituals. If a family member dies, the family performs a funeral ritual. This ritual allows them to face the reality of the death and their emotions. A Buddhist priest approaches the family of the deceased at this point, and the family members rebuild their relationships through the ritual along with the Buddhist priest, other mourners, and the deceased. Thus, two conclusions can be reached. First, family members rebuild their relationships and stabilize them through communication with a Buddhist priest, other mourners, and the deceased. Whether they have a positive attitude toward the ritual does not matter. Second, rituals for the deceased are meaningful to family members because thinking of death allows them to sense the preciousness of life.

Eclipseとは天体現象である日蝕や月蝕の‘蝕’を意味する.近年,左室駆出率が保たれた患者に,明らかな誘因なく一過性にごく短時間生じる急性機能性僧帽弁逆流の報告がなされ,Eclipsed mitral regurgitation(MR)と称されている.症例は60歳代女性.突然の胸部不快感にて救急受診した.来院時,心電図にて広範な誘導でのST低下を認め,また高感度心筋トロポニンTが0.131 ng/mLと上昇していた.心エコー図では左室駆出率は保たれていたが,左室基部に限局した全周性の壁運動低下および新規の重症MRを認めた.冠動脈造影では有意狭窄病変は認めなかった.ニトログリセリン持続投与開始後,胸部症状は消失し,翌日には心電図変化,心エコー図での左室基部の壁運動異常およびMRともに消失していた.以後も胸部症状や心電図変化,MRの再燃なく経過し,2週間後の外来時には高感度心筋トロポニンTも正常値となっていた.本症例の病態として,たこつぼ症候群(Basal type)や冠攣縮性狭心症の可能性も考慮されるが,いずれも典型的とはいえず,その臨床像および経過はEclipsed MRの報告例と酷似していた.Eclipsed MRは稀な病態ではあるが,重症例や再発例の報告もあり,本疾患の存在を理解しておくことは重要と考え,ここに報告する.

In the Himalayas, domesticated yak is fed at an altitudinal range of 3,000 to 5,000m. Below this zone, the cow is more common. Hybrids are fed at an intermediate zone. In order to analyze the genetic basis of milk protein variation, milk samples were taken from the nak (female yak), cow and their hybrid. By principle component analysis, yak and a highland type of cow (kirmcome) were clearly distinguished from midland (shakzam) and lowland (palang) cows. Local Sherpa people may produce suitable animals for each zone by controlling animal reproduction systems. Generally speaking, a sustainable stocking rate is two adult animals per hectare in the central Himalayas. However, most pastures were overgrazed 3 to 10 times more than this level. The feedstuff stored over winter was half composed of hay and half of agricultural by-products such as rice straw and wheat straw. Grazing by animals provided 53 to 60 % of food intake (fresh plant weight). Ten % of fodder was provided by trees. For the total number of animals in this study region, the fodder shortage was very acute. Overpopulation of animals was estimated to be 31 to 73 %. Tree fodder is a typical feedstuff in this region. Popular fodder trees are Quercus, Symplocos and Castanopsis. Extention programmes are needed to increase tree fodder production and conserve soils. Ten years are needed to establish a system for continuous tree fodder production. One fodder tree can produce 14 kg fresh matter per year. The shortage can overcome by planting an additional 10 to 15 fodder trees per cow.
