Effect of transmembrane potential on noradrenaline transport in chromaffin granules]

Imposing a transmembrane potential positive with respect to the medium on chromaffin granule ghosts increased the initial rate of the delta pH-induced uptake of noradrenaline, whereas imposing a negative potential decreased this rate. The increase of the uptake rate was proportional to the potential. The ATP-induced uptake of noradrenaline was also sensitive to the potential since imposing a transient negative potential onto the positive potential generated by the membrane ATPase induced a latency in this transport.     

Étude biochimique des poissons: 2. Variations semestrielles de la teneur en glycogène,en lipides totaux et en minéraux du tissu musculaire de la truite Arc-en-ciel (Salmo gairdnerii Rich)

Summary The variations of glycogen, lipids and ashes in muscular tissue of the Rainbow trout (Salmo gairdnerii Rich.) show that during sexual cycle there are 4 periods. Each period corresponds to a particular biological activity. The sexual activity cannot explain all the modifications of glycogen content.
