Assuming in Equation 1 that AMPK activation was not affected by the level of glycemia, the mathematical modeling demonstrated that EMD008 caused an upward shift of the linear relationship between glucose disposal and blood glucose concentration without affecting its slope, i.e., EMD008 treatment increased cellular glucose uptake, no matter what the actual level of glycemia is (Figure 2A).
Hysteresis levels were observed as a shift of the phase relationship between stress and strain waveforms.
First, dofetilide caused a shift of the whole relationship towards higher amplitude of HF oscillations in HR (horizontal shift).
This is visible as parallel downward shift of the dose response relationship for nicotine/menthol.
It was reported that a concurrent leftward shift of the I O relationship curve and increase in mIPSC frequency reflect an enhancement of GABA release (Herman et al., 2013).
The present study provided evidence for an increase in GABAergic influence on VLPAG neurons in the FBC model, indicated by a leftward shift of the I O relationship curve of GABAergic eIPSCs, facilitation of GABAergic eIPSCs by paired stimuli, and the enhanced frequency of spontaneous mIPSCs.
When the stimulus intensity was gradually increased, electrical stimulation gave rise to larger-amplitude eIPSCs at a lower intensity in the FBC model than the sham-operated mice, indicating a leftward shift of the I O relationship curve of eIPSCs in slices of the FBC model = 9.098; P < 0.05.
In slices from the FBC model, GABAergic synaptic transmission at VLPAG neurons was enhanced, as indicated by a leftward shift of the input output relationship curve of evoked IPSCs, the increased paired-pulse facilitation and the enhancement of miniature IPSC frequency.
The salt-sensitive Dahl S (SS) rat is a widely studied example of an animal that develops hypertension, associated with a shift of the pressure-natriuresis relationship (relationship between sodium excretion and arterial pressure) to higher pressures, when fed a high-salt diet.
