Although the need to assess hydration is well recognized, laboratory tests and clinical
impressions are impractical and lack sensitivity, respectively, to be clinically meaningful …

In response to background illumination, the adaptation properties of the b-wave are similar
to those observed in the human eye with psychophysical methods. With increasing …

The constant phase element (CPE) is a capacitive element with a frequency-independent
negative phase between current and voltage which interpolates between a capacitor and a …

Previous measurements have shown that the electrical properties of the squid axon
membrane are approximately equivalent to those of a circuit containing a capacity shunted …

Abstract Troponin, a Ca2+-sensitive complex, regulates the motions of tropomyosin on the
thin filaments in many muscles. It has three subunits, each with a different architecture and …

John C. Gerhart and Howard K. Schachman abstract: Kinetic investigations of regulatory
enzymes have led to the current view that such enzymes bind their regulatory metabolitesat …

ALLOSTERIC REGULATION OF ENZYME ACTIVITY 43 tabolism and the characterization of
the enzymes that catalyze the multistep reaction sequences involved, has set the stage for …

Binding of genome regulatory proteins to nonspecific DNA sites may play an important role
in controlling the thermodynamics and kinetics of the interactions of these proteins with their …

The actin-tropornyosin interaction was studied by means of light-scattering. The
experimental data were analysed on the basis of the model of co-operative binding of large …

The cortical cytoplasm, including the cleavage furrow, is largely composed of a network of
actin filaments that is rigid even as it is extensively deformed during cytokinesis1, 2. Here we …
