    Estimation of Distance Changes Between Cys-964 and Lys-501 in Na+/K+-ATPase Intermediates and the Orientation of Transmembrane Segment Containing Cys-964

    Na+/K+ -ATPase (EC.3.6.1.3) from pig kidney was modified with N-(p-(2-benzimidazolyDphenyl)- maleimide (BIPM) and fluorescein 5’-isothiocyanate (FITC), which react primarily with Cys-964 and Lys?-501 (11,14). The...

    Oxygen Diffusion Through Mitochondrial Membranes

    The membrane viscosity of myocardial mitochondria was measured recently with a time-resolved fluorescence technique. As expected from the low concentration of cholesterol in mitochondrial membranes, the viscos...

    Diffusion Pathway of Oxygen in OX Lung

    Since hemoglobin in erythrocytes in the lung capillary is separated from alveolar air by pneumocytes, vascular endothelium, the blood plasma layer and the erythrocyte membrane, inhaled oxygen molecules diffuse...

    Dynamic Structure of Phospholipid Bilayers on the Path for Oxygen Diffusion in the Ox Lung

    The dynamic properties of the phospholipid bilayer of cell membranes were studied with a nanosecond fluorometer to obtain information on the microstructure of the path for oxygen diffusion in the ox lung. The ...

    Oxygen Diffusion Coefficient of Cell Membranes

    The microviscosity was measured in erythrocyte membranes of different animal species and in lung cells and myocytes of bull frogs by means of the nanosecond fluorescence depolarization technique with a rod-lik...

    Hypoxic Reduction in Blood Flow Velocity in Pulmonary Arterioles and Capillaries

    The vasoconstrictory effects of hypoxia on pulmonary circulation are well established. The ventilation of a single lung lobe with nitrogen causes a reduction in the blood flow in the hypoxic lung lobe. However...

    Peroxidases

    A brief description is made of properties of a wide variety of peroxidases which illustrates differences as well as similarities. The article begins with monoheme enzymes and ends with myeloperoxidase and Pseu...
