Sleep problems are known to be risk factors for subsequent emotional and behavioral difficulties in childhood adolescence. To date, there has been no study investigating the relationships between sleep habits a large nonclinical sample of preschool age children. The aim this was examine these associated with (2 5 year old) Their mothers (n = 1,746) completed multiple-choice questionnaire about behavior their children, as well own working hours at Tokyo metropolitan public nursery schools....
Longitudinal studies in Japan indicate that nocturnal sleep onset has become later and duration been progressively shortened. This study aimed to investigate the relationship between patterns problems among children, determine association parents their children's habits. Questionnaires about life habits were administered families living Tokyo metropolitan areas of Japan. We analyzed data pre-school-age (1-5 years old; n = 319, including 175 girls) elementary school-age children (6-11 years;...
Applications of the GFP-fusion technique have greatly facilitated evaluations amounts and qualities sample proteins used for structural analyses. In this study, we applied GFP-based evaluation to secreted protein expression by insect cells. We verified that a GFP variant, GFPuv, retains proper folding monodispersity within all spaces in Sf9 cells, such as cytosol, organelles, even extracellular space after secretion, thus can serve reporter recombinant proteins. then GFPuv-based system...
Abstract Background Lactococcus lactis subsp. cremoris (YRC3780), which is isolated from kefir, has been associated with anti-allergic effects in humans. However, it remains unknown whether daily intake of YRC3780 attenuates the response to psychological stress humans parallel changes gut microbiome. We examined fundamental role microbiome, response, sleep, and mental health Methods Effects on hypothalamic-pituitary-adrenal (HPA) axis acute were investigated a double-blind,...
Abstract Several studies have reported that some people the ability to awaken from sleep without using external means. This is called ‘self‐awakening’. The present study investigated sleep/wake habits of university students with or a habit self‐awakening. Of 643 students, 66 (10.3%) habitually self‐awakened in daily life. In comparison those who did not self‐awaken ( n = 577, 89.7%), self‐awakening went bed and woke up approximately 30 min earlier, felt better when they morning, dozed off...
The relationship between generalized self-efficacy and afternoon napping with or without self-awakening, defined as waking up at a designated time decided before sleep, was investigated in elderly people. It has been reported that short nap self-awakening can reduce sleepiness sleep inertia. feeling of self-control over may contribute to maintaining daily life. In the present study, questionnaire survey conducted 447 people aged 65 (74.3±5.28). A one-way analysis variance compared four...
<title>Abstract</title> In the present study, we investigated 70 elderly individuals with dementia residing in a group home Japan (88.1±6.6 SD years; 12 males and 58 females). Sleep measurements were collected via an accelerometer placed under mattress from March 2021 to January 2024. The accelerometer-derived activity counts transformed plotted as actograms. On basis of actograms, sleep patterns categorized into three groups: regular nighttime (Type 1, n=38, 54.3%), daytime naps 2, n=29,...
本研究では習慣的自己覚醒が夜間睡眠に及ぼす効果を検討した.朝, 習慣的に自己覚醒している13名の被験者が2夜の実験夜に参加した.1夜は強制覚醒夜で, 被験者は習慣的な起床時刻に実験者によって強制的に起こされた.もう1夜は自己覚醒夜で, 被験者は習慣的な起床時刻に自己覚醒を試みた.就床直前の不安, 夜間のポリグラフ記録, さらに起床直後の睡眠の主観的評価が分析された.19夜の自己覚醒夜のうち, 自己覚醒に成功したのは8夜 (42.1%) であった.不安, 睡眠の主観的評価, 睡眠段階1の出現量以外の睡眠変数には, 強制覚醒夜と自己覚醒夜の間で有意差は認められなかった.これらの結果は, 習慣的自己覚醒は夜間睡眠, 起床後の気分, 睡眠満足感を悪化させないことを示唆している.
眠気の日内変動には，起床6から8時間後に高まる眠気（午後の眠気）と夜間就寝前にむけて高まる眠気（夜間の眠気）が存在する。夜間の眠気は，脳内の生物時計中枢の制御を受ける深部体温の概日リズムに起因する。一方，午後の眠気の発生機序については不明である。本研究では，眠気に関わる生理的要因として末梢皮膚温，深部体温，自律神経活動に注目し，眠気と生理的要因との関係性を明らかにすることを目的とした。その結果，5名中4名の実験参加者において，起床3時間後以降に2から5時間毎の眠気の変動が観察された。起床後0―2時間および就寝時刻付近の眠気は深部体温，皮膚温，自律神経活動と有意な相関が認められた。一方，午後の眠気については個人差が大きく，体温，自律神経活動と一貫した相関関係は認められなかった。これらの結果から，眠気の日内変動に存在するウルトラディアンリズムは体温と自律神経活動の概日リズムに依存しないが，起床後および就寝前の眠気は，主に概日リズムを発振する生物時計中枢の制御を受けることが推測された。
