Depolarzation

To partially or completely eliminate or counteract the polarization of. Looking for online definition of depolarization in the Medical Dictionary? Meaning of depolarization medical term.

What does rapid depolarization mean? It may also refer to the result of such action so that the result is an unpolarized condition.

Depolarization is the process or the act by which polarity is eliminated.

Imaging of brain slices revealed immediate early induction of β-actin transcription after depolarization.

Small currents flow from this source through the aqueous medium containing the cell and are detectable at considerable . Anoxic depolarization is induced by the loss of neuronal selective membrane permeability and the ion gradients across the membrane that are . Many cells use electrical stimulation to communicate with each other. This process starts with depolarization. The lesson looks at the role of. The yeast actin cytoskeleton is polarized during most of the cell cycle. Certain environmental factors and mutations are associated with depolarization of the actin cytoskeleton.

Meyer-Franke A(1), Wilkinson GA, Kruttgen A, Hu M, Munro E, Hanson MG Jr, Reichardt LF, Barres BA. Moreover, we review recent evidence to suggest that other derangements may also contribute to the pathophysiology of Brugada syndrome, in particular, right ventricular structural derangements. In reviewing these studies, we conclude . English, psychology and medical dictionaries. Recordings from dopamine neurons in rats have revealed that chronic antipsychotic drug treatment in the time-dependent inactivation of dopamine neuron firing via over-excitation, or depolarization block.

Furthermore, the clinical profile of the response to antipsychotic drugs appears to correspond to the dopamine . How spreading depolarization can be the pathophysiological correlate of both migraine aura and stroke. To further assess the role of membrane interactions, we measured membrane depolarization in Gram-positive bacteria with different membrane lipid compositions, as well as in Gram-negative bacteria. We found greatly increased membrane depolarization at the minimal bactericidal concentration of the . The stroke-migraine depolarization continuum. Pathophysiological mechanisms of Brugada syndrome: depolarization disorder, repolarization disorder, or more? Meregalli PG(1), Wilde AA, Tan HL.

In Raman spectroscopy, the depolarization ratio is the intensity ratio between the perpendicular component and the parallel component of the Raman scattered light. Early work in this field was carried out by George Placzek, who developed the theoretical treatment of bond polarizability. The Raman scattered light is emitted . The values obtained from Asian and .
