A kinetic diagram of these states is above each configuration of the channel. Ion channels in the cell membrane open or close depending on the cell membrane potential. When a channel is in an open state, specific ions are allowed to flow down their electrochemical gradient. The process of ...
To measure their initial emotional reaction to selected scenes and provide a better estimation of the impact of subsequent TNT manipulation on affective responses, participants first performed an emotion rating task. This task consisted in rating both the valence and the arousal associated with each vi...
Fig. 8: Schematic diagram depicting the mechanisms by which MI-induced reduction of Ndufs1 leads to cardiac dysfunction by exacerbating mitochondrial dysfunction and apoptosis. MI-induced Sp1 reduction decreases Ndufs1 transcription in the nucleus. Ndufs1 reduction in mitochondrial complex I increase ...
The heart is regulated by both neural and endocrine control, yet it is capable of initiating its own action potential followed by muscular contraction. The conductive cells within the heart establish the heart rate and transmit it through the myocardium. The contractile cells contract and propel the...
Cardiac repolarization activity may be mapped using action potential duration (APD) and/or excitatory recovery interval (ARI). APD may be measured, for example, using a bipolar electrogram signal measured using a monophasic action potential (MAP) catheter. ARI may be measured using a monopolar ...
F, simplified free energy diagram illustrating that the hypothesized mutation-induced shift of the auto-inhibitory equilibrium toward the inactive state may arise either from a stabilization of the inactive state and/or from a destabilization of the active state. This scheme assumes that the state-...
N01: I don't like the little diagram. I just think it's confusing, sorry. We have them in nursing all the time and I hate them. I just don't feel that that really adds anything. Participants were positive about the relaxation techniques. The nurses thought it was espe- cially good...
Figure 1. Trial flow diagram of acupuncture in persistent AF. Patients received active acupuncture or sham acupuncture treatment according to the assigned sequence and AF recurrence was assessed. AF recurrence was evaluated using 48-h Holter monitoring, electrocardiography, and follow-up echocardiography....
They suggested that in these myocytes, a voltage-driven mechanism was possible due to the steep action potential duration restitution curves. In this study we use our local-control model of the rat ventricular myocyte to study the interplay of calcium-dependent and voltage-dependent mechanisms to ...
CCS generation stage of the development process of a 3D cardiac computational model. Diagram outlining several ways to generate a model of the CCS to be coupled to a 3D cardiac model. It shows the information sources (blues boxes), the partial results obtained (grey boxes) and the methods (...
