The mean (±SD) FMD was 5.60 ± 2.15 FMD% of the baseline diameter.
The mean baseline diameter of the basilic veins was 5.1 mm (± SD 1.3 mm).
Thirty min were allowed between each of these treatments for recovery to the baseline diameter.
It is defined as the percentage dilation from the baseline diameter in response to a provoked increase in blood flow.
However, the baseline diameter of arterioles from ovariectomized rats (63 ± 4 μm) was significantly smaller than the diameter of arterioles from control rats (75 ± 3 μm, p < 0.05).
It is possible that despite ensuring that the vein returned to within ± 0.1 mm of its baseline diameter between different maneuvers, recovery time may have been inadequate.
Vasopressin so administered attenuated pial artery dilation to these K+ channel activators under conditions of equivalent baseline diameter during non injury conditions (13±1 and 23±1 vs. 4±1 and 10±2% for cromakalim 10−8, 10−6 M before and after vasopressin, respectively).
Analysis showed that there is an increased risk (odds ratio of 3) with a hypersensitive pupil response (≥13% increase in pupil diameter over baseline diameter) for developing significant cognitive impairment in areas of memory attention and language in a pattern, consistent with pre-clinical Alzheimer's disease.
Measurement of FMD and FID were given as the relative increase in diameter in percent compared to the baseline diameter of the brachial artery.
On one of the days we measured the following: 1) baseline diameter and volume with no exogenous challenge; and followed by 2) measurements after total lung challenge with aerosolized histamine.
For participant 1 (19 yo F), the baseline post-illumination pupil response plateau was 5.83 mm at 3.5 h (25.0% constriction relative to baseline diameter), increasing to 7.18 mm at 15.4 h (7.5% relative constriction) (Figure 2A).
