AbstractThe transport of RNA from the ganglion cell bodies within the retina to the contralateral optic tectum has been studied in the chick following intraocular injection of radioactive uridine. By tracing the appearance of labeled RNA at the proximal end of the optic nerve as it leaves the eyeball and comparing this to the time of arrival of RNA ...

Simulation of axoplasmic transport
Journal of Theoretical Biology, 1984We have analysed a kinetic model of axonal transport by simulating experimental tracer profiles. The existence of three phases of axoplasmic transport is assumed: fast anterograde, slow anterograde and retrograde. Each phase has its characteristic velocity. Transported materials are postulated to shift between these phases.

Axoplasmic Transport and Neurological Surgery
Neurosurgery, 1982Both the slow bulk flow (1 mm/day) of cytoplasm and the rapid transport of specific small molecules, as well as macromolecules (at rates of up to 410 mm/day), are known to occur in the neuronal cell body, axon, and dendrites. The basic phenomena as well as mechanisms of these transport phenomena and their implication for a variety of pathophysiological

Axoplasmic transport in aged rats
Experimental Neurology, 1982Abstract The velocities of 3H-proteins undergoing fast axoplasmic transport in sciatic nerves were measured in rats of different ages with close attention paid to temperature regulation during the period of transport. The rate of axoplasmic transport slowed from a high of 453 ± 15 mm/day at 3 months of age, to 406 ± 16 mm/day in the 37- to 38-month ...

Slow axoplasmic transport: a fiction?
Journal of Theoretical Biology, 1985Ribosomes have not been observed in axoplasm. This had led to the notions that the perikaryon is the only source of neuronal proteins and that the axoplasm is supplied by a (slow) transport mechanism. However, we question these two notions because they are unable to give an account of real neurones in accordance with the body of biological knowledge ...

Functional recovery of axoplasmic transport of regenerative peripheral nerve promoted by FK506
, 2011Objective To explore the effect of FK506 (tacrolimus) on functional recovery of axoplasmic transport of the regenerative peripheral nerve.Methods Forty-eight Sprague-Dawley rats with 10 mm gap of sciatic nerve were randomly divided into 2 even groups.The

Inhibition of fast axoplasmic transport by acrylamide
Environmental Research, 1978The effect of acrylamide on fast axoplasmic transport in the cat sciatic nerve was studied in vivo and in vitro by the technique of isotope injection. [14C]leucine was injected into the lumbar dorsal root ganglia. In cats fed daily doses of acrylamide over 1 to 4 weeks, the rate of transport was 286 mm/day compared with 424 mm/day in controls. In vitro

Calcium and the Mechanism of Axoplasmic Transport
1978Using desheathed cat peroneal nerves in in vitro studies, Ca2+ was recently shown to be required to maintain axoplasmic transport. Calmodulin was also shown to be present in nerve and to participate in transport. These findings open up new possibilities for a better understanding of the underlying mechanism of transport. In the transport filament model,
