Motion Analysis System Using Motion Capture and 3D Computer Graphics
The Japanese Journal of Ergonomics, 2009 本研究では，直観的に理解しやすい動作解析を行うための，動作解析システムの開発を目的とする．提案システムは，光学式モーションキャプチャにより動作を，無線式生体アンプにより筋電信号を測定する．可視化は，人体の骨格形状，筋肉の位置や形状を正確に反映した3次元コンピュータグラフィックス（3DCG）人体アバターが，モーションキャプチャで測定した動作を再現し，その動作に伴う筋活動の大きさを筋肉の色で表現するものである．提案システムは，従来の動作解析システムと比較し，動作と生体状態を同時に可視化するため，身体全体の総合的評価，および，生体状態の時間変動評価に適している．3DCGを用いた可視化のため，動作を任意の注視点から観測することができる．本論文では，動作解析システムの構成，可視化手法 ...

Clinical Validation of Plasma p‐217tau in Neurological Diseases
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Plasma p‐217tau is a minimally invasive but specific biomarker for diagnosing Alzheimer's disease (AD). However, its disease specificity remains to be clinically evaluated. We validated the reliability of the p‐217tau biomarker in 12 other neurological diseases.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

SPG4 and Dementia: Expanding the Clinical Spectrum
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.
