Plasmalemma-enriched vesicles were isolated from cotton roots (Gossypium hirsutum L. cv Acala San Jose 2) and from germinating radish seeds (Raphanus sativa L. cv Tondo Rosso Quarantino). When 100 millimolar ascorbate was added to the grinding medium, the addition of ferricyanide to either preparation led to an inside positive membrane potential as measured(More)
The fact that a statement has scientific credibility only to the extent that it is confirmed makes it desirable to examine clinical confirmation of clinical hypotheses of the type that, when presented to patients in psychoanalysis or psychotherapy, commonly are referred to as interpretations. An attempt is made to show that clinical confirmation in(More)
Uptake of the lipophilic cation triphenylmethylphosphonium into mesophyll protoplasts of oat (Avena sativa L. cv. "Garry") approaches equilibrium at 3 to 4 hours. The resulting external and internal concentrations are then used with the Nernst equation to obtain a membrane potential of -62 millivolts, inside negative. Potentials calculated in this manner(More)

In this lecture we continue our exploration of martingales through their application to random graph coloring and random geometric TSP. We shall see how Azuma's(More)
Methods used in preparing Arbacia eggs for respiration studies, in carrying through the manometric determinations, and in estimating egg quantities have been reexamined. Discrepancies in previous results are almost entirely due to a steady error in measuring egg volume by centrifuging. Volumes so obtained averaged 80 per cent too high. The respiration of(More)
