Synthetic lubricants and lubricating oil additives.

Journal of The Japan Petroleum Institute, 1988
著者が行ってきた合成潤滑油および添加剤の研究を紹介する。1)ポリオールエステル2種類の混合基油を用いて高温安定性のすぐれた7808Fグレードジェットエンジン油を開発した。2)2-エチルヘキサノール製造時に副生するC16エーテルは高粘度指数作動油の基油としてすぐれている。3)ポリC1～C4アルキルメタクリレートは芳香族りん酸エステルに可溶であり, 粘度指数向上効果をもつ。4)チオりん酸亜鉛とアミンとは錯体をつくる。錯体は4種類ある。油中で解離平衡状態にあり, 解離度はアミンの立体障害と塩基度により決まる。錯体の合潤中での耐摩耗性はその熱安定性よりも金属表面への吸着性に支配される。

Mitochondrial Dysfunction Unravels the Potential Molecular Link Between Night Shift Work‐Related Circadian Disruption and Elevated Blood Pressure in Human and Mouse Models

Advanced Science, EarlyView.
This diagram illustrates that night shift work disrupts circadian clock genes (like CLOCK, BMAL1) in both humans and mice. This disruption leads to mitochondrial dysfunction (imbalanced fusion/fission proteins) and increased oxidative stress, which is identified as the primary mechanism ultimately causing elevated blood pressure.
