Papers
1. Takafumi Maeda, Hiroko Koga, Takashi Nonaka, Shigekazu Higuchi, Effects of bathing-induced changes in body temperature on sleep, Journal of Physiological Anthropology, https://doi.org/10.1186/s40101-023-00337-0, 42, 20, 2023.09, [URL], 人の生活活動である入浴に伴う体温変化が睡眠に及ぼす影響を明らかにした研究である。本研究では、舌下温0.9℃の上昇をもたらす浴槽浴はシャワーのみや0.3℃上昇の浴槽浴よりも、入眠時間を短縮し睡眠の質を向上させることを明らかにした。睡眠が不足している現代人の睡眠の質向上に資する研究である。.
2. Nishimura T, Motoi M, Toyoshima H, Kishida F, Shin S, Katsumura T, Nakayama K, Oota H, Higuchi S, Watanuki S, Maeda T, Endocrine, inflammatory and immune responses and individual differences in acute hypobaric hypoxia in lowlanders, Scientific Reports, https://doi.org/10.1038/s41598-023-39894-w, 13, 12659, 2023.08, この研究では、健康な低地住民を対象に急性低圧低酸素環境に曝露中の内分泌、炎症、免疫パラメータの変化と個人差を調査した。 曝露後、アルドステロンとコルチゾールは大幅に減少し、インターロイキン (IL)-6、IL-8、白血球 (WBC) 数は大幅に増加した。末梢酸素飽和度 (SpO2) の低下は、IL-6 および WBC 数の増加と関連し、IL-8 の増加はコルチゾールの増加と関連した。これらの発見は、低圧低酸素への 75 分間の短い曝露でも内分泌、炎症、免疫反応が誘発され、SpO2 が低い人はより顕著な反応を示すようであることを示唆した。.
3. Keneth B Sedilla, Takafumi Maeda, Autonomic thermoregulatory responses and subjective thermal perceptions upon the initiation of thermal behavior among resting humans in hot and humid environment, Journal of Physiological Anthropology, https://doi.org/10.1186/s40101-022-00308-x, 41, 1-9, 35, 2022.10, 本研究は、高温多湿の環境において体温調節行動を開始する際の自律体温調節反応の活性化と主観的な温熱知覚を解明することを目的とした。体温調節行動の開始前に核心体温、平均皮膚温、温熱的不快感、皮膚濡れ感は増加したが、皮膚血流量や局所発汗量は増加しなかった。これらの発見は、高温多湿の環境で温熱行動を開始するのは皮膚の血流と発汗量の変化ではなく、体温の変化と熱的不快感の増加であることが示唆した。.

Yoshiki Yasukochi, Sora Shin, Hitoshi Wakabayashi, Takafumi Maeda, Upregulation of cathepsin L gene under mild cold conditions in young Japanese male adults., Journal of Physiological Anthropology, https://doi.org/10.1186/s40101-021-00267-9, 40, 16, 2021.10, 人類の出アフリカ後の環境、特に寒冷環境への適応は人の生理的体温調節機構を理解する上で重要な要素となっている。 最近の研究では、寒冷適応に関与するさまざまな遺伝子が特定されているが、急性寒冷曝露に応答した初期体温調節の基礎となる分子機構は依然として不明である。 そこで、我々は急性寒冷ストレスにさらされた日本人若年男性6人の転写プロファイルを調査した。
人工気候室において、気温 28°C に 65 分間維持し、その後 70 分間で 19°C まで徐々に低下した前後に 唾液サンプルを採取し、RNA配列を調査した。
寒冷ストレスに対する唾液中の転写反応の鈍化により転写変化の程度は高くなかったものの、14の遺伝子の発現レベルが有意に変化した[誤検出率(FDR) 1 であった。 したがって、この遺伝子は差次的に発現される遺伝子として同定されました。 カテプシン L タンパク質が新型コロナウイルス (SARS-CoV-2) の侵入に関連していることを考えると、軽度の寒冷ストレスによってヒトのコロナウイルス感染症 19 に対する感受性が変化する可能性が考えられる。以上から、FDR この研究から得られた結果は、CTSL 発現レベルが急性の軽度の寒冷ストレスによって変化する可能性があることを示している。.
