Lead activates calmodulin sensitive processes
(Elsevier, 1983-09-05)
The effect of lead on two calcium sensitive processes was determined. Micromolar concentrations of lead successfully replaced calcium in the activation of calmodulin-sensitive phosphodiesterase and in the promotion of ...
Linkage of the structural gene for uroporphyrinogen I synthase to markers on mouse chromosome 9 in a cross between feral and inbred mice
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1982-08)
The Ups locus has been mapped to mouse chromosome 9 in a three-point cross. The observed gene order is centromere- Ups -15- Mpi-1 -22- Mod-1 . Ups is unlinked to Lv , which encodes the previous enzyme in the heme biosynthesis ...
Visual detection by the rod system in goldfish of different sizes
(Elsevier, 1988)
New rods are continually generated and inserted across the entire differentiated retina in juvenile and adult goldfish; no other retinal cells share this characteristic. How does the preferential addition of rods affect ...
A quantitative study of retrograde axonal transport in motor and sensory neurons
(Elsevier, 1986-04)
We used 3H N-succinimidyl propionate to covalently label in vivo proteins of the rat sciatic nerve, and studied the accumulation of radioactively labeled proteins in the cell bodies of the ipsilateral dorsal root ganglion ...
Degenerative and regenerative changes in the trochlear nerve of goldfish
(Kluwer Academic Publishers; Chapman and Hall Ltd ; Springer Science+Business Media, 1984-08)
The features of unlesioned and lesioned trochlear nerves of goldfish have been examined electron microscopically. Lesioned nerves were studied between 1 and 107 days after cutting or crushing the nerve. 1. Unlesioned nerves ...
Macronuclear persistence of sequences normally eliminated during development in Tetrahymena thermophila
(Wiley Subscription Services, Inc., A Wiley Company, 1985)
During conjugation in the ciliated protozoan, Tetrahymena thermophila , a somatic MAC-ronucleus develops from the germinal MICronucleus. Ten to 20 percent of the MIC genome is eliminated during this process. Three repetitive ...
Culturing spinal cord explants in a collagen gel
(Elsevier, 1984-08)
A new method for culturing spinal cord slices or explants is presented which entails the use of a commercially available purified collagen, Vitrogen. Vitrogen provides a stable three-dimensional matrix for culturing spinal ...
Calmodulin distribution in peripheral nerve: an EM immunocytochemical study
(Elsevier, 1988-12-20)
We used electron microscopic immunocytochemistry to study the distribution of calmodulin in rat sciatic nerve. Calmodulin immunoreactivity was found throughout the axoplasmic matrix, but particularly along microtubules. ...
A signal generator for testing extracellular recording amplifiers and probes
(Elsevier, 1988-10)
A portable signal generator that simulates the amplitude and frequency of neuronal signals for testing extracellular recording amplifiers is described. The signal generator is easy to construct and it is extremely useful ...
