Effect of Water Vapor on CO2 Separation Performance of Membrane Separator.
KAGAKU KOGAKU RONBUNSHU, 1999 飽和水蒸気を含むCO2, N2混合ガスからCO2を中空糸膜モジュールを用いて分離する実験を行った.膜モジュールを透過したガス中のCO2/N2モル比は水蒸気を含まない混合ガスからCO2を分離した場合よりも大きかった.モジュール内のガスのプローパターンで比較すると飽和水蒸気を含む混合ガスからのCO2分離は並流の方が向流よりも優れていた.コンピューターシミュレーションによりモジュール内の気体の挙動を解析した結果, 水蒸気の膜透過速度がCO2に比べて大きいため飽和水蒸気を含むことにより膜の透過側のCO2モル分率が小さくなり, CO2の分離推進力が大きくなることが判った.また, 並流ではモジュール内の全領域に水蒸気が存在するのに対し ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
