Exosomes are now considered to have multiple functions, including immune regulation, distribution of cell substances, and propagation of prion proteins and retroviruses (Ritchie et al., 2013).
Truth, context, and discussion are secondary to means of propagation.
Phenylethylamine (PEA), tyramine and tryptamine are the presently known endogenous CAE/SAE substances which enhance the impulse propagation mediated release of catecholamines and serotonin in the brain.
The strongly confined mode which decays both evanescently along transverse to propagation direction interacts with the substance while propagating along the PC-air interface.
During seed treatment, chemical or biological substances are applied to seeds or vegetative propagation materials to control disease organisms, insects or other pests.
(A) indicates the number of replicates in which Physarum propagated toward substance A, (B) indicates the number of replicates in which Physarum propagated toward substance B, (N) indicates the number of neutral propagation events for that binary mixture of chemicals, whereas FTP indicates the number of replicates where Physarum failed to propagate from the inoculation site.
In either case, the mechanism of action potential propagation and release of synaptic transmitter substance is the same.
Active substances with an unspecific inhibitory action against IV propagation--regardless of the viral subtype--would probably not lead to resistance, if such IVs do not evade inhibition by changes in their viral properties [ 17].
Although a number of simplified models for the gas lift system can capture the main feature of the casing-heading phenomenon, most of them assume that the substances in the tubing are homogeneous, which ignores the propagation phenomenon.
TE is a non-invasive imaging method that calculates liver stiffness via measurement of the propagation of an elastic shear wave through the liver substance.
