RNA Metabolism during Regeneration in Stentor coeruleus1
The ciliate protozoan, Stentor coeruleus, has been a favored organism in which to investigate nucleo-cytoplasmic relationships during intracellular regeneration and reorganiza tion. The morphology of stentors and the changes that occur during regeneration and division have been described in detail and were reviewed in Tartar's (1961) treatise. Studies of either regenerative or replicative morph...
متن کاملMacronuclear differentiation during oral regeneration in Stentor coeruleus.
The moniliform macronucleus of Stentor coeruleus coalesces and renodulates during division, reorganization and regeneration. These nuclear events are spatially and temporally synchronized with oral primordium development occurring at stages six and seven of membranellar morphogenesis. Coalesced, elongating and early renodulating macronuclei at states six and seven contained microtubules within ...
متن کاملnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
15 صفحه اولCalcium and Calmodulin Antagonists Delay Oral Regeneration in the Ciliate Stentor Coeruleus
The regeneration of a new oral apparatus in Stentor coeruleus (oral regeneration) has been shown to be sensitive to events that inhibit calcium uptake and calmodulin function. Removal of extracellular calcium delays oral regeneration significantly. The calcium channel antagonist verapamil also delays oral regeneration, as does lanthanum, which is known to block calcium uptake. Both inhibitors a...
متن کاملStentor coeruleus
What is Stentor coeruleus? Stentor coeruleus is an astoundingly large (~1 mm long) single-celled pond organism with a distinct trumpet shape and a well-defined morphology (Figure 1). The name Stentor is a reference to its trumpet shape and the herald in Greek mythology known for having a loud voice, while coeruleus describes the blue–green pigment specific to the species. Abraham Trembley, who ...
