Transient expression, more frequently referred to "transient gene expression", is the temporary expression of genes that are expressed for a short time after nucleic acid, most frequently plasmid DNA encoding an expression cassette, has been introduced into eukaryotic cells with a chemical delivery agent like calcium phosphate (CaPi) or polyethyleneimine (PEI). [1]
Damped oscillation is a typical transient response, where the output value oscillates until finally reaching a steady-state value. In electrical engineering and mechanical engineering, a transient response is the response of a system to a change from an equilibrium or a steady state.
In systems theory, a system is said to be transient or in a transient state when a process variable or variables have been changed and the system has not yet reached a steady state.
This causes brief hyperpolarization of the membrane, that is, the membrane potential becomes transiently more negative than the normal resting potential. Until the potassium conductance returns to the resting value, a greater stimulus will be required to reach the initiation threshold for a second depolarization.
Le(a+b+) phenotype is transiently observed in infants (Secretor activity increases with age). [7] This phenotype is also encountered in 16% of Japanese individuals (who inherit a weak Secretor gene- Se(w)). In absence of a functional Lewis gene (lele), neither Le(a) nor Le(b) are synthesized, leading to the Le(a-b-) phenotype.
A simple smiley. This is a list of emoticons or textual portrayals of a writer's moods or facial expressions in the form of icons.Originally, these icons consisted of ASCII art, and later, Shift JIS art and Unicode art.
Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs. Instead, a phosphorescent material absorbs some of the radiation energy and reemits it for a much longer time after the radiation source is removed.
In the physiological sense of "parabiosis," "para" apparently was intended to mean "next to." In describing transiently inactive physiological states, "para" apparently meant "outside of." In ecological usage, the word was coined by the entomologist Auguste-Henri Forel as an analog to "symbiosis," also in the sense of "next to." However, in ...
