The average low-dose maximum stimulation was approximately 50% greater than controls.
While the maximum stimulation was observed already at 2 μM ATP, 0.2 μM did not induce stimulation of NCXK4 activity.
The maximum stimulation was achieved at 750 μM and this concentration was used in all further experiments.
VEGF-E showed a similarly strong effect at all concentrations tested, whereas maximum stimulation was seen below the highest concentrations with P lGF-1 (at 1 and 10 ng/ml) or P lGF-2 (at 1 ng/ml; Fig. 1).
After a 15 minute equilibrium period, muscle length was adjusted to Lo (the length at which force generation was maximum), stimulation current was adjusted to supramaximal levels and a force-frequency curve was constructed by stimulating strips at 1, 10, 20, 50, and 80 Hz (train duration 800 msec) with a 30 second rest period between adjacent stimulus trains.
Regarding this last aspect, inter-individual variability in the anatomy of the occipital region and in skull thickness may represent another potentially relevant source of clinical heterogeneity and, to some extent, may be responsible for the impossibility of perceiving phosphenes by some subjects, even when maximum output stimulation is performed [39].
The antioxidant activity of jaboticaba was investigated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis 3-ethylbenzothiazoline-6-sulphonic 2,2′-azinobis 3-ethylbenzothiazoline-6-sulphonic 2,2′-azinobis 3-ethylbenzothiazoline-6-sulphonic 2,2′-azinobis 3-ethylbenzothiazoline-6-sulphonic 2,2′-azinobis 3-ethylbenzothiazoline-6-sulphonic
Meanwhile, the maximum stimulation effects were found between 4 and 8 h.
When the threshold (or the maximum stimulation time) was reached, stimulation stopped automatically (therefore, we use the term adaptive stimulation), followed by 5 minutes without stimulation.
Maximum stimulation intensities were pre-determined by measuring the stimulus and fiber volley magnitudes necessary produced the maximum fEPSP magnitudes during basal input/output measurements.
