Utilisation de la centrifugation analytique pour la mesure, au sein d'un extrait brut d'E. coli, du coefficient de sédimentation du complexe de décarboxylation oxidative du pyruvate.
We have applied successfully the active enzyme analytical centrifugation method (A.E.C.) to the study of the well known pyruvate dehydrogenase complex (P.D.C.) in crude extracts from E. coli. It is not possible to study the complex in a spectrophotometer (through its dehydrogenase activity) due to NADH oxidase activities. The A.E.C. method, which overcomes this difficulty, can also be viewed as a refined spectrophotometric method.

Differential cerebral processing of noise and verbal stimuli.
Psychophysiological measurements have indicated that the right cerebral hemisphere processes noises and other nonverbal data and that the left cerebral hemisphere processes verbal material. Direct physiological measurements, as expressed in summated auditory evoked cortical responses, unequivocally demonstrate that click noises show a greater amplitude of initial output over the right brain, and that verbal stimuli produce either equal or higher amplitudes of output over the left cerebral hemisphere.
