An ideology is defined as a set of ideas that “explains and evaluates social conditions, helps people understand their place in society, and provides a program for social and political action” (Ball & Dagger, 2011, p. 4). As such, these concepts underpin the actions of various groups and organizations, including that of the Anonymous hacker group ...

Potentiation of Epinephrine Action
Nature, 1961THE following experimental results have been reported by our colleagues on the potentiation of epinephrine action by various substances, clarifying part of its mechanism : (1) The potentiation of epinephrine action on vasoconstriction by certain amino-acids was attributed to a reaction in which the oxidized form of epinephrine gave rise to the ...

Neurobiology of Learning and Memory, 2000
Neurons compute in part by integrating, on a time scale of milliseconds, many synaptic inputs and generating a digital output-the "action potential" of classic electrophysiology. Recent discoveries indicate that neurons also perform a second, much slower, integration operating on a time scale of minutes or even hours.

New Progestins and Potential Actions
Journal of the Society for Gynecologic Investigation, 2000Newer, nonsteroidal, orally active, tissue-selective progestins are being developed through a molecular approach to compound selection with human progesterone receptor (hPR) serving as the molecular target. The co-transfection and binding assays are used to test receptor selectivity and cross reactivity with a panel of receptors.

“Metabolic” action potentials inAcetabularia
The Journal of Membrane Biology, 1976The transient depolarizations in Acetabularia which fulfill the essential criteria of an action potential (all-or-none characteristics, triggering by depolarization, propagation, etc.) are investigated. These action potentials are analyzed by conductance measurements and voltage clamp experiments on the basis of the analog circuit of the membrane ...

Action Potential in Charophytes
2007The plant action potential (AP) has been studied for more than half a century. The experimental system was provided mainly by the large charophyte cells, which allowed insertion of early large electrodes, manipulation of cell compartments, and inside and outside media.
